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
