Question 934331: Jason drove 150 km at 100 km/hr to a stampede. Then she drove back home at 80 km/hr. What is the difference in time between the trips. Explain Answer by TimothyLamb(4379) (Show Source):
You can put this solution on YOUR website! a = time going
b = time returning
---
s = d/t
t = d/s
---
time going:
a = 150/100
---
time returning:
b = 150/80
---
b - a = 150/80 - 150/100
b - a = 0.375 hours
b - a = (0.375 hours) * (60 minutes/hour)
b - a = 22.5 minutes
---
answer:
it took 22.5 minutes more to return than it did to go, due to the slower return speed
