Question

Lance runs 14.5 miles in 2 hours 45 minutes. To the nearest tenth what is Lance speed in miles per hour ?

Answer 1

Okay so speed is distance over time, but your time has to be converted into hours first.

Answer 2

45 minutes is 0.75 hrs, so the total number of hours is:
2+0.75 = 2.75 hrs

Answer 3

Now just use distance over time:
Speed = 14.5mi/2.75hrs = 5.272727...mph
To the nearest tenth that's 5.3 mph

Answer 4

Thank You
