Let the number of trees planted by the fifth grade students be X
1.5X-X=75
X=150
Therefore, the number of trees planted by sixth grade students: 150 + 75 = 225
Suppose there are X cards
2X+3X+X=96
X=16
Therefore, Liangliang has: 16 × 2 = 32 sheets
Strong: 16 × 3 = 48

1. A car goes from place a to place B at the speed of 30 kilometers per hour. Four hours later, a train goes from place B to place a, and the speed of the train is three times that of the car. At a distance of 450 kilometers from city B, the train meets the car. How many kilometers are there between the two places?
2. The two cars run from east to west at the same time. Car a runs 56 kilometers per hour and car B 48 kilometers per hour. The two cars meet at 32 kilometers from the midpoint. How many kilometers is the distance between East and West?
Step by step calculation process to write!

1.30 * 3 = 90 km / h 450 / 90 = 5 h 30 * (4 + 5) = 270 km 270 + 450 = 720 km
720 km apart
