Car a and car B start from a place 300 kilometers away to B place. Car a starts 1.5 hours later than car B. as a result, the two cars arrive at the same time. The speed ratio of car a and car B is 5:4, and car a starts 1.5 hours later than car B How many kilometers does the car travel per hour

Car a and car B start from a place 300 kilometers away to B place. Car a starts 1.5 hours later than car B. as a result, the two cars arrive at the same time. The speed ratio of car a and car B is 5:4, and car a starts 1.5 hours later than car B How many kilometers does the car travel per hour

Suppose: Vehicle B travels 4x kilometers per hour, while vehicle a travels 5x kilometers per hour
300/4x=300/5x +1.5
15/x=1.5
x=10
4x=40,5x=50
A: car a travels 50 kilometers per hour

A and B vehicles start from a to B 240 km away from a at the same time. It is known that the speed of a vehicle is 20 km faster than that of B vehicle per hour. As a result, a vehicle arrives 60 minutes earlier (1 hour). What is the speed of a and B vehicles
To list the equations and the steps to solve the problem

Let the speeds of a and B be a and B respectively
A = B + 20;
240/A+1=240/B;
A = 60km / h; b = 40km / h
