Problema Solution
Jessie drove at a constant speed for 200 miles. Then it started to rain. So for the next 90 miles she traveled 5 miles per hour slower. The entire trip took 6 hours of driving time. Find her speed for each part of the trip. Fill in the chart and state your solutions
Answer provided by our tutors
Her speed for part 1:x
Her speed for part 2:(x-5)
So the equation is
200/x + 90/(x-5) = 6
So
x = 50
So
Her speed for part 1: 50 mph
Her speed for part 2: 45 mph
