On your wedding day, you leave for the church 25 minutes before the ceremony is to begin. the church is 8 miles away. on the way, you have to make an unanticipated stop for construction work. as a result, your average speed for the first 15 minutes is only 7 miles per hour. what average speed in miles per hour do you need for the rest of the trip to get to the church in time

V=37.5miles/h

Explanation:

For convenience, let's convert the average speed to miles per minute:

V=7miles/h * 1h/60min = 0.1167 miles/min.

The distance traveled during the first 15 min was:

D = V*t = 1.75 miles   So, the remaining distance is 6.25miles.

Since you only have 10min left:

Vr = Dr / tr = 6.25 / 10 = 0.625 miles / min. If we take that to miles per hour we get final

Vr = 0.625 miles/min * 60min/1h = 37.5 miles/h
