Today's Question - Get me to the church on time. Bob and Ann are headed for a friend's wedding. If Bob drives at his usual 60 mph, they'll get there 1 hour too early. If Ann drives (30 mph), they will be an hour late. How far away is the wedding? What speed should they drive to get there on time?

Corner Answer - The Wedding Trip - The distance was 120 miles and the "correct" speed should be 40 mph. The "hour early"/"hour late" difference was 2 hours (120 minutes). The difference in speeds was 1 minute per mile (60 mph = 1 mile per minute vs. 30 mph = 1 mile per 2 minutes). So 120 minutes equals 120 miles. To get to the wedding on time (3 hours) the right speed is 40 mph.Doesn't match Missing info Like question
