Answer:
60m
Explanation
Given that, speed of car P and Q is vp=10m/s,vq=15m/s
Length of each car =5m
and separation between the cars=90m
Total distance covered(d)=90+5+5=100m
Relative velocity(v)=10+15=25m/s
Time taken(t)=dv=10025=4s
Distance traveled by Q,(dp)=vp×t=15×4=60m
Hence, the distance moved by the car Q during the time interval in which they completely cross each other is60m
