Answer:
Speed = Distance/Time. so if you rearrange this it means that you get Time = Distance/Speed. Therefore 240/60 = 4 then you just think of doing miles(distance)/Miles per hour(speed) which leaves you with 4 hours which=C
Step-by-step explanation:
Sometimes to make it easier i use a triangle from this equation, you cover up what one you want and then you do what it says. If you cover up distance then you are left with speed x time. Likewise if you cover up speed. Speed = Distance / Time.
