Question

City M is 600 km from City N. A bus drives 60 km/h and a truck

drives 50 km/h along the road between City Mand City N. How
long after the truck should the bus start driving if they want to
meet in the midpoint of the road?

Answer 1

After 2h s

Explanation:

The the whole journey is 600 km from city M to N. So the mid point would be 300 km

The bus takes 5 h to reach the mid point of the road ( 300 km ÷ 60 km/h = 5 h)

And the truck takes 6 h to reach the mid point of the road ( 300 km ÷ 50 km/h = 6 h)

So if they want to meet each other the bus should start its journey one hour after the truck.
