Problema Solution

Write an equation that can be used to solve this problem. Jake’s school bus averages 28 mi/h, including stops. One day Jake left his coat at home. His mom left home 15 minutes (0.25h) after Jake and traveled an average speed of 42 mi/h. How long did it take Jake’s mom to catch the bus?

Answer provided by our tutors

let t = the time Jake's mom needed to catch the bus


the bus travels 0.25h longer then Jake's mum or: t + 0.25


since speed = distance/time follows distance = speed*time


28*(t + 0.25) = t*48


by solving we find


t = 0.35 h


t = 0.35*60 = 21 min
