First, let's find out how long it takes for each of you to travel 50 km.
For you:
time = distance / speed
time = 50 km / 88.5 km/h = 0.5649717514 h
For your friend:
time = 50 km / 94.5 km/h = 0.5291005291 h
Now, we will subtract your friend's time from your time to find how long your friend will wait for you:
time_difference = 0.5649717514 h - 0.5291005291 h = 0.0358712223 h
Now, we want the answer in minutes, so we'll convert hours to minutes:
0.0358712223 h × (60 min / 1 h) = 2.152273338 min
Your friend will wait for you for about 2.15 minutes at the end of the trip.
You and a friend each drive 50 km to the same destination. You travel at 88.5 km/h and your friend at 94.5 km/h.
How long will your friend wait for you at the end of the trip?
