Party A and Party B go from place a to place B at the same time, and Party A goes to place B after 10 hours, which takes 4 hours more than Party B. It is known that the speed difference between the two is 5 kilometers per hour How many kilometers per hour? The solution of the equation

Party A and Party B go from place a to place B at the same time, and Party A goes to place B after 10 hours, which takes 4 hours more than Party B. It is known that the speed difference between the two is 5 kilometers per hour How many kilometers per hour? The solution of the equation

Suppose that a travels x kilometers per hour and B travels x + 5 kilometers per hour
10x=（10-4）×（x+5）
10x=6x+30
4x=30
x=7.5
7.5 + 5 = 12.5km
A: A: 7.5km per hour; B: 12.5km per hour

Party A and Party B go from a to B at the same time. Party A arrives at B after 10 hours, which takes 4 hours more than Party B. It is known that the speed difference between them is 5 kilometers per hour
How many kilometers per hour do people travel? (the process should be clear)

Distance between the two places 5 △ 1 / (10-4) - 1 / 10
=5÷【1/6-1/10】
=5÷1/15
=75 km
A speed of 75 △ 10 = 7.5km/h
B speed 7.5 + 5 = 12.5km/h
