Question 1001811: On an automobile trip, Laura Iossi maintained a steady rate for the first two hours. Rushhour traffic slowed her rate by 25 mph for the last part of the trip. The entire trip, a distance of 125 mi, took 2 hr. What was her rate during the first part of the trip?

You can put this solution on YOUR website!
First part x mph
time = 2hours
second part (125-2x)
speed = (x-25)
time for second part = (125-2x)/(x-25)
Total time = 2 hours
how is it possible?
