540÷9/2-68
=52 (km)
A: trucks travel 52 kilometers per hour



The speed ratio of truck and bus is 3:4. The two cars leave from both places at the same time and meet at the place 12 kilometers away from the destination. How many kilometers is the distance between the two places?


It's the midpoint, right
If so: 12 × 2 ÷ (4-3) = 24 km
24 × (3 + 4) = 168 (km)
A: the distance between a and B is 168 kilometers



Car a and car B run from a and B at the same time. Car a runs 56 kilometers per hour and car B runs 48 kilometers per hour. The two cars meet at 32 kilometers from the midpoint. How many kilometers is the distance between a and B?


A: the distance between a and B is 832 km



The distance between a and B is 230 kilometers. A and B leave at 8 a.m. at the same time. A travels 40 kilometers per hour, B 52 kilometers per hour. When do the two cars meet


230 / (52 + 40) = 2.5,8 + 2.5 = 10.5,10:30
