A- 8 min.
EDIT: If he runs 5 kilometers in 20 minutes then divide 20 by 5 to figure out how many minutes it takes him to run 1 kilometer. Multiply that by 2 and you get your answer.

Start by setting this up as a ratio: 5/(20 )=2/x the units are kilometers over minutes. Then you cross multiply, and you get 5x=2(20). This becomes: 5x=40. Then you divide on both sides and your solution is x=8 minutes. So the answer is A

The answer is A
Its easy to understand. Just think 2 is less than half of five which means your answer will be less than half of twenty and the only answer that is less than half of twenty is 8. Its that easy! Hope this helps :)

Mark runs 5 km in 20 min
20 min = 20/60 = 1/3 of an hour
5 / (1/3) = 2 / x
5x = 2/3
x = 2/15 hours or 2*4 / 15 * 4 = 8 / 60 or 8 minutes.
20 min = 20/60 = 1/3 of an hour
5 / (1/3) = 2 / x
5x = 2/3
x = 2/15 hours or 2*4 / 15 * 4 = 8 / 60 or 8 minutes.

5 km = 20 minutes
2 km = x minutes
x = 20 * 2 / 5
x = 40 / 5
x = 8 minutes
so the answer is A. 8 minutes
2 km = x minutes
x = 20 * 2 / 5
x = 40 / 5
x = 8 minutes
so the answer is A. 8 minutes

He runs 15 kilometers per hour. Divide 60 by 15 to find the time it takes to run one kilometer. Multiply that times 2 and you get 8 minutes.

A.
2/5=0.4
0.4*20 = 8
2/5=0.4
0.4*20 = 8
