Back to paper

A truck travels to a town at 30 km/h and returns at 20 km/h. If the total time taken is 5 hours, what is the one-way distance to the town?

Show answer & explanation

Correct answer: C

Explanation

Speed ​​while going = 30 km/h
Speed ​​while returning = 20 km/h
Total time = 5 hours
Let the distance for one side be x km.
Time taken while going = x/30
Time taken while returning = x/20
x30+x20=52x+3x60=55x60=5x12=5x=60\frac{x}{30} + \frac{x}{20} = 5 \\ \frac{2x + 3x}{60} = 5 \\ \frac{5x}{60} = 5 \\ \frac{x}{12} = 5 \\ x = 60
Distance for one side = 60 km
