A team of cyclists rode from place a to place B at the speed of 24 kilometers per hour. Two hours later, a motorcycle also ran from place a to place B at the speed of 56 kilometers per hour, catching up with the cyclists at half of the distance between place a and place B. Q: the distance between place a and place B is long______ Kilometers
After two hours, the distance between cyclists and motorcycles: 24 × 2 = 48 (km), the time for motorcycles to catch up with athletes: 48 △ 56-24 = 1.5 (H), the distance for motorcycles: 56 × 1.5 = 84 (km), the distance between a and B: 84 × 2 = 168 (km); a: the distance between a and B is 168 km

Q: the distance between place a and place B is long______ Kilometers
After two hours, the distance between cyclists and motorcycles: 24 × 2 = 48 (km), the time for motorcycles to catch up with athletes: 48 △ 56-24 = 1.5 (H), the distance for motorcycles: 56 × 1.5 = 84 (km), the distance between a and B: 84 × 2 = 168 (km); a: the distance between a and B is 168 km
The distance between a and B is 42 km. Xiaoming starts from a to B by bike at the speed of 20 km / h, and then starts from B by motorcycle 0 or 4 hours later
equation
Xiao Gang and Xiao Ming are going together
42-20 × 0.4 = 34 km
Xiao Gang and Xiao Ming go together every hour
34 △ 0.5 = 68 km
Xiao Gang can do it every hour
68-20 = 48 km
