The distance between a and B is 480 km. Two cars leave each other at the same time and meet each other after 5 hours. One car travels 56 km per hour, and the other car travels how many km per hour?
480 △ 5-56 = 96-56 = 40 km a: another car travels 40 km per hour
The distance between a and B is 480 km. Two cars leave each other at the same time and meet each other after 5 hours. One car runs 56 km per hour, and the other car runs how many km per hour?
480 divided by 5-56 = 96-56 = 40
Car a and car B leave 480 kilometers apart. Car a travels 64 kilometers per hour, while car B travels 56 kilometers per hour. How many hours do the two cars meet when they start at the same time?
Equation method
Suppose: two cars start at the same time and meet in X hours
(64+56)x=480 64x+56x=480
120x=480 120x=480
x=4 x=4
Arithmetic:
480÷（64+56）
=480÷120
=4 (hours)
The two cars started at the same time and met in four hours
Car a and car B run from two places 270 kilometers apart and meet each other in 1.5 hours. Car a runs 80 kilometers per hour, while car B runs 80 kilometers per hour
How many kilometers per car? Solve by equation
270 △ 1.5-80 = 100 km / h
