At the same time, Party A and Party B set out to travel to a place 40 kilometers away. Party A rides a bike and Party B drives a car. As a result, Party B was earlier than Party A 1 hour for 20 minute

At the same time, Party A and Party B set out to travel to a place 40 kilometers away. Party A rides a bike and Party B drives a car. As a result, Party B was earlier than Party A 1 hour for 20 minutes. Solution: If the bicycle speed is X, the car speed is 3X.

40/x=40/3x+4/3

(Time spent riding a bike = time spent driving +4/3 hours)

Solve the above one-dimensional linear equation and get X=20.

3X=60

A: The speed of cars is 60 kilometers per hour, and that of bicycles is 20 kilometers per hour. ..
