Question

Steve ran a 12-mile race at an average speed of 8 miles per hour. If Adam ran the same race at an average speed of 6 miles per hour, how many minutes longer did Adam take to complete the race than did Steve?

Answer 1

the picture is the formula.

D stands for distance

S stands for speed

T stands for time

Explanation:

Steve

Time = Distance divided by speed

=12miles divided by 8miles per hour

=1.5hours or 90minutes

Distance= 12miles

Speed= 8miles per hour

Adam

Speed= 6miles per hour

Distance= 12miles

Time= distance divided by speed

= 12miles divided by 6miles per hour

=2hours or 120minutes

120minutes - 90minutes=30 minutes
