The speed the second car is catching up with the first will be the difference in the speeds: 90-70 = 20km/h
Using the formula speed=distance/time, which we can rearrange by multiplying both sides by time and dividing both sides by speed:
time=distance/speed
Distance: 500m =0.5km
So, time (in hours) = 0.5/20 = 0.025 hours
There are 60 minutes in an hour, so in minutes the time will be 60x0.025 = 1.5 minutes.
So the answer is 1 1/2 minutes.
