The distance between a and B is 500 kilometers. A truck and a minibus leave each other at the same time. After 4 hours, they meet. It is known that the truck travels 45 thousand kilometers per hour How many kilometers does the minibus travel per hour? Lie equation
500÷4-45
=125-45
=80km
Passenger cars travel 80 kilometers per hour
At the same time, the passenger cars and freight cars run in opposite directions from a and B, and meet 45 kilometers away from the midpoint. The speed ratio of the passenger cars and freight cars is 3:2. How many kilometers is the distance between a and B
Distance difference = 45 + 45 = 90 km
Distance = 90 ÷ (3-2) × (3 + 2) = 450 km
