This question is simply conversions
we know there are 100 cm in a m so..
50 × 100 = 5,000 cm/s
and we know there are 1,000 m in a know so..
50 ÷ 1,000 = 50/1,000 = 1/20 km/s
Answer:
0.08 minutes for a kilometer.
Step-by-step explanation:
If the track is 25 kilometers, and he runs 25 kilometers in 2 minutes, he runs a kilometer in 2÷25 minutes or 0.08 minutes which is 4.8 seconds.
I'm pretty sure the track isn't 25 kilometer or he can't run a lap in 2 minutes. But if so, the answer is 0.08 minutes.
