Challenge: On a map with ratio of 4:10000, a road is 12cm long. a) How long is the road on the ground.?

Part (a)\n4:10000 scale means 4 cm distance on map represents 10000 cm or 100 m. Hence a 12 cm road is actually (12*100/4) = 300 m = 0.3 km long.\n\nPart (b)\nLength scale 4:10000 means area scale is (4*4):(10000*10000) i.e. 16:10^8. This means 10^8 cm^2 area will be represented by 16 cm^2 area on the map. Hence 3.2 km^2 = 3.2*10^10 cm^2 actual area is represented by (16*3.2*10^10/10^8) = 5120 cm^2 area on the map.

1) two hours from 9 to 11. so distance 45*2 = 90 km\n\n2) The car has done 100+108= 208 km in 5 hours\nthe speed is 208/5 = 41.6 kph

3.36 meters.  \n\nHere's why:  find the formula for the parabola.  We know that when X is 0, Y is 4.  And, we know that when X is 2.5, Y is 0.  So the formula is:\n\nY = 4 - (4/6.25)*X^2.\n\nNow let X = 1 (half the width of the truck), you'll see Y is 3.36.

1 kilometer = 100 000 centimeters\n\nso we have\n\n200: 100000\nor\n1:500

Just "m" (always lower case)\n\n1 km = 1000 m

120\nx.25\n------\n3000\n\n~~move decemal point over two places so the answer is 30.00 or can be written 30~~

20m/s.\nbecause the total time is 5s. and by defn of average speed it is the ratio of total distance travelled to total time taken i.e 100/5 = 20m/s

2000 kilometers=2000*1000 meters(1km=1000m)\nnow 2000*1000 meters=2000*1000*100 centimeters\nNow you know that 1 inch =2.54 centimeters\nthere for dividing the above value (in cm) by 2.54 you will get  78740157.48 inches. That is approximately equal to 78740157.5 inches.\nTherefore 2000 kilometers=78740157.5 inches

u dont need the 6 in this question because all the tyres travel the same amount. (its juss there 2 throw u)\nso then all we have to do is go:\n\n 16000(distance travelled) / (tht means divide)8 (amount of wheels)= 2000 (basic division)

You need to explain where points R,S,P,Q are.  All that is certain from your information is that LM is 120/13 and KM is 12.

They travelled a total of 476 miles in 4 hours.  So together they are travelling (476/4) mph or 119 mph.\n\nSo you have two equations:\nJ + S = 119\nJ - S = 5\n\n2J = 124\nJ = 62 mph\nS = 57 mph

Compared to its floor mgh = 0 because h=0\nCompared to the street mgh > 0, since h>0\n\nCompared to its floor (1/2)mv2 = 0 because v(rel) = 0\nCompared to the street (1/2)mv2 > 0 because v = v(truck)\n\nTh

There are 12 inches in a foot.\n\nSo divide by 12.

My first answer would be 22.5 paces away from E, which is 45 paces from the road\n\n\nUsing a co-ordinate system; with A (0,0); B(0,0); C(240,100); D(240,0) where North is positive y\nSince by Pythag (Asqd + Bsqd = Csqd)  gives y co-ord of B as root(300sqd-240sqd)= 180 and likewise y co-ord of C is root(260sqd-240sqd) = 100\n\nUsing m=[changein]y/[changein]x (sorry no delta sign)\n\nGive eq of AC as 100/240x\nand eq of BD as -300/240x+180\n\nE is where 100/240x = -300/240x + 180\n implies  400/240x = 180\n therefore x co-ord of E = 108\nAC implies 100/240(108)= 45 paces from the road AD on the x axis\n\nE therefore 22.5 paces from treasure.

1. D. 4000 g. because there are 1000 grams in a kilogram.\n\n2. B. 15 ft. 7 in. because you just have to add the feet and then add the inches (14 ft. 19 inches) and then change twelve of the inches into one foot. \n\n3. C. 10 hr. 20 min. because it is 8 hr. 20 min. from 3:40 AM to noon, and it's 2 more hours to 2:00 PM. \n\n4. A. 8,800 yd. because there are 1,760 yards in one mile, and then you just multiply by 5. \n\nI hope this helps. Don't just copy the answers, but make sure you UNDERSTAND the material. :)

It is 1 kilometer (1000 meters). Roughly 3281 feet or .62 miles.
