Answer:
1.5 minutes
Explanation:
The time it takes for you to drive a distance of 53km at 88.8 km/h is
t = s/v = 53 / 88.8 = 0.5968 hours
Similarly the time it takes for your friend to drive a distance of 53km at 92.6 km/h is
53 / 92.6 = 0.572 hours
Obviously since it takes less time for your friend, he will arrive first if both of you start at the same time. His waiting time would be
0.5968 - 0.572 = 0.0245 hours or 0.0245 * 60 = 1.5 minutes
