Question

Tim takes 3 hours to reach his destination traveling at a constant speed of 12 miles per hour. How long will it take Tim to reach his destination if he travels at a constant speed of 15 miles per hour?

Answer 1

2.4 hours

Explanation:

note

speed= distance/time

Step one:

given data

Tim takes 3 hours to reach his destination traveling at a constant speed of 12 miles per hour.

time= 3 hours

speed= 12mph

distance covered= speed*time

distance covered= 12*3

distance covered= 36 miles

Step two:

The distance remains the same

if time drives at 15mph

we are expected to find the time Tim took

time= distance/velocity

time= 36/15

time= 2.4 hours
