Annie drives between two towns at an average speed of 40 mph.

Tariq drives between the same two towns on the same route at an average speed of 25 mph.

Annie leaves the first town at 9 am and arrives at the second town at 10:30 am.

If Tariq sets off at the same time, what time does he arrive at the second town?

1 answer

Tariq's speed is 5/8 as fast as Annie's
So, he takes 8/5 as long
8/5 * 3/2 = 12/5 = 2:24
So Tariq arrives at 11:24
