Answer 2

How fast are they moving apart, if they are going in opposite directions and one goes 40 mph and the other goes 35 mph?

Answer 3

After one hour, the first friend will be 40 miles away from the starting point. The second friend will be 35 miles away from the starting point, in the other direction. That means they are now separated by how many miles?

Once you figure that out, divide 150 miles by the number of miles they separated in 1 hour, and you'll have the number of hours it takes to get 150 miles apart.
