Two cars set out from a certain place at the same time to transport a batch of goods to the construction site 165 kilometers away. Car a arrived 48 minutes earlier than car B. when car a arrived, car B was 24 kilometers away from the construction site. How many hours did car a spend on the whole journey?

Two cars set out from a certain place at the same time to transport a batch of goods to the construction site 165 kilometers away. Car a arrived 48 minutes earlier than car B. when car a arrived, car B was 24 kilometers away from the construction site. How many hours did car a spend on the whole journey?

48 minutes = 0.8 hours; 24 △ 0.8 = 30 (km / h); 165 △ 30-0.8, = 5.5-0.8, = 4.7 hours; a: it took 4.7 hours for car a to complete the whole journey

48 minutes = 0.8 hours; 24 △ 0.8 = 30 (km / h); 165 △ 30-0.8, = 5.5-0.8, = 4.7 hours; a: it took 4.7 hours for car a to complete the whole journey

A and B trucks set out from a certain place at the same time to transport a batch of goods to the farm 165 kilometers away. Car a arrived 0.8 hours earlier than car B. when car a arrived, car B was still 24 kilometers away from the farm, and car a spent the whole journey______ Hours

24 △ 0.8 = 30 (km); 165 △ 30-0.8 = 5.5-0.8, = 4.7 (H); so the answer is: 4.7

Two cars set out from a certain place to the same destination at the same time, the distance is 165 kilometers. Car a arrives 0.8 hours earlier than car B. when car a arrives at the destination, there is still time to get off
Continue above: when car a arrives at the destination, car B is 24 kilometers away from the destination. How many hours did car a spend on the whole journey?

Let the speed of car B be y, y * 0.8 = 24, y = 30
Vehicle B: 165 / 30 = 5.5
If car a arrives 0.8 hours earlier than car B, the time of car a is 5.5-0.8 = 4.7
