It takes 8 hours to travel 128 miles
Explanation:
Using ratio
miles per hour
But the target is 120 miles so we need to change the 15 into 120.
Multiply by 1 and you do not change the value. However, 1 comes in many forms so you can change the way something looks without changing its true value.
So it takes 8 hours to travel 128 miles
