The road from a to B is 384 kilometers long. Two cars leave each other. Car a travels 38 kilometers per hour and car B 42 kilometers per hour. Car a starts 64 kilometers before car B starts. How many hours after car B starts, do the two cars meet?
(384-64) △ 38 + 42, = 320 △ 80, = 4 (hours); a: the two cars meet 4 hours after the second car leaves
One highway is 348 km long. Two cars drive from the two places. Car a travels 38 km per hour and car B 42 km per hour. Car a drives 64 km first,
B car just started. After what time did the two cars meet?
348-64 = 284km 284 * (42 + 38) = 3.55h
