You didn't ask all your questions, did you

The car travels 68 kilometers per hour, and the speed of the car is twice that of the truck. They drive in opposite directions from two places 357 kilometers apart. (1) after meeting for several hours. (2) how many kilometers do the two cars travel when they meet. (3) if it's 8:45 when they start, when they meet

（1）357÷（68+68÷2）
=357÷102
=3.5 (hours)
(2) When we met, the car went: 68 × 3.5 = 238km
Truck line: 357-238 = 119 km
(3) 3.5 hours = 3:30
If the departure time is 8:45, the meeting time is: 8:45 + 3:30 = 12:15
