Question

In 2009, a Jamaican sprinter named Usain Bolt set a world record when he ran 100 meters in 9.58 seconds (or 0.160 minutes). If a car traveled at that average speed for 1 hour, how far would it travel?

The distance traveled in one hour is equal to the distance traveled in one minute times the number of minutes in an hour.

But I cannot figure out the answer!!! It's way to hard for me, and normally, I'm really ggood at this kind of thing. But today, I just can't seem to do it?!? I'm actually really annoyed about it!!!!

Answer 1

Answer:

37,500 m

Step-by-step explanation:

Given Usain bolt traveled 100m in 0.160 minutes

recall that

speed = distance travelled ÷ time taken

hence Usain Bolt's speed

= 100  m ÷ 0.160 min

= 625 meters per min

Now given that a car travels at the same speed for one hour.

recall 1 hour = 60 minutes.

Using the same formula as above

speed = distance traveled ÷ time taken

rearranging, we get

distance traveled = speed x time taken

we calculated the speed previously to be 625 m/min and we are given a time of 1 hour (i.e 60 min)

hence

distance traveled = speed x time taken

distance traveled = 625 m/min x 60 min = 37,500 m
