You and a friend each drive 63 km to the same destination.
You travel at 89.7 km/h and your friend at 97 km/h.
How long will your friend wait for you at the end of the trip?
Answer in units of min
:
Let w = time your friend waits for you
Find the time required by each of you to go 63 km, ans will be in hrs, convert to min, mult by 60.
:
w = 63%2F89.7 - 63%2F97
w = .70234 - .64948
w = .05285 * 60 = 3.17 minutes
