A batch of goods was sent to Party A and Party B according to the ratio of 5:3. Party a finished four fifths of the team, and the rest was sent to Party B. Party B transported 48 tons in total. How many tons are there in total?

A batch of goods was sent to Party A and Party B according to the ratio of 5:3. Party a finished four fifths of the team, and the rest was sent to Party B. Party B transported 48 tons in total. How many tons are there in total?

A total completion = 5 △ (5 + 3) × 4 / 5 = 1 / 2, total = 48 ± (1-1 / 2) = 96 tons

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

A and B drive from a to B at the same time. Four hours later, B arrives at B and exceeds a by 56 kilometers. It is known that a travels 80 kilometers per hour. How many kilometers per hour does B travel?

The whole length is
80 × 4 + 56 = 376 (km)
Car B runs every hour
376 △ 4 = 94 (km)

Car a and car B drive from the same place to the same direction at the same time. Car a runs 56.5 kilometers per hour, and car B runs 45.5 kilometers per hour. After a few hours, the distance between the two cars is 132 kilometers. The solution is given by equation and arithmetic

1. Set 56.5x-45.5x = 132 after X hours
We get x = 12
2.132÷(56.5-45.5）=12
