A and B leave from two places 585 kilometers apart at the same time. A travels 65 kilometers per hour and B 52 kilometers per hour. How many hours later do they meet
585 ÷（65 +52）
=585 ÷ 117
=5 hours
Car a and car B travel from two places 360 kilometers apart and meet each other in 4 hours. Car a travels 35 kilometers per hour, and car B travels how many kilometers per hour?
360 divided by 4-35 = 55
