A freight car travels 48 kilometers in 6 / 7 hours. According to this calculation, the freight car travels (56) kilometers in 1 hour
A truck can travel 48 kilometers in 6 / 7 hours. According to this calculation, a truck can travel (56) kilometers in 1 hour, and it takes (1 / 56) hours to travel 1 kilometer. Great Xia, please explain in detail how the answer is worked out

48 divided by 6 is one seventh of an hour
Multiply that by seven and you'll get an hour's drive
That is 48 / 6 * 7 = 56 km
Driving 56 kilometers an hour, 1 kilometer is 1 / 56 hour, then 2 kilometers is 2 / 56 hour
And so on, 56 km takes 56 / 56 hours, which is one hour
