If Lokesh valks to school and rides his bicycle back home it takes him 90 minutes. If he rides his bicycle both ways it takes him 30 minutes. How many hours would it take him to make the trip to school and back by walking?
2 hours 30 minutes.
Exactly correct answer. It will be very useful to others if you could publish the solution.
From the 2nd line: For 2 way in bicycle, it takes 30 minutes. So for 1 way it will take 15 minutes.
From the 1st line: By walk + By bicyle = 90 minutes; By walk = 75 minutes.
Solution: 2 way by walk = 150 minutes which is 2 hours 30 minutes.
2 hours and 30 minutes
Walk + Ride = 90 minutes
Ride + Ride = 30 minutes
Ride = 15 minutes
Walk + 15 = 90 minutes
Walk = 75 minutes
Walk + Walk = 150 minutes
Walk + Walk = 2 hours and 30 minutes
