Suggested Answer: C 🗳️
Define X as the average speed to the country club and Y as the average speed on the way back.
The average speed of the entire round trip to the club is 87.5% of the average speed on the way to the club:
(X + Y) / 2 = 0.875X,
X + Y = 1.75X,
Y = 0.75X.
The average speed on the way back is 75% of the speed to the club.
If the time it takes her to get to the country is T, then T/0.75 is the time it will take to get back home.
50/0.75 = approximately 66 minutes.
