You can put this solution on YOUR website! Jonathan drove 160 miles in the same time that Alicia drove 100 miles. Find
Jonathan’s speed if he was driving 10 miles per hour slower than twice Alicia’s
speed?
let x=Alicia's speed
2x-10=Jonathan’s speed (10 miles per hour slower than twice Alicia’s speed?)
travel time=distance /speed (same for both drivers)
160x=100(2x-10)
160x=200x-1000
40x=1000
x=25
2x-10=50-10=40
Jonathan’s speed=40 mph
