12 / 48 = 0.25 times

A bicycle travels 12 kilometers per hour, and a motorcycle travels 1 kilometer per hour. It takes 3 minutes less than a bicycle. How many times is the speed of a motorcycle?

1 hour = 60 minutes, the speed of motorcycle: 1 △ 60 (60 △ 12-3) × 60, = 1 △ 2 × 60, = 30 (km / h); the speed of motorcycle is that of bicycle: 30 △ 12 = 2.5; answer: the speed of motorcycle is 2.5 times that of bicycle

If x = 52, the speed of bicycle is () km / h

12 hours

A car travels 70 kilometers per hour. Xiaogang's speed of riding a bicycle is 4 kilometers less than 2 / 7 of the car's speed. How many kilometers does Xiaogang travel per hour?
2 / 7 = two out of seven

Xiaogang's speed of cycling per hour = 70x2 / 7-4 = 14-4 = 10km
