Physics homework?
Can anyone give me a solution to the following problem?
A 5-meter-long car attempts to overtake a truck. They are traveling at a constant speed of 108 km/h and 72 km/h, respectively. The distance between the vehicle tips is 60 meters.
– After what time and at what distance from the starting point are both vehicles at the same height?
– What is the distance between the vehicles after 10 seconds?
There is no sketch and I don't understand where to start… Thanks in advance 🙂

First a change of the reference system. The truck stands and the car drives the difference of 36 km/h. 36 km/h are 10m/s (which is a coincidence!). 60m in 6 seconds.
I find this unhappy with the vehicle tips. Is that both the front bumper?
If it is the front, after 6 seconds the two front ends of the vehicles are side by side.
10 seconds are a hundred meters. The car is 5m long, so are 35m distance from the truck.
Thanks for the quick help! I didn’t quite understand that with the vehicle tips, it seems to mean the front. (Have also friends so balanced) Thank you
