Question

If i start my trip driving at x mph for a hours and then go 5 mph slower for the next 2 hours what is the total distance i traveled.

Answer 1

Total distance travelled = (x.a + 2x -10) miles .

How to solve such time related questions?

The key concept for solving such questions is the relationship between speed, distance and time.

The relationship between them is Distance = Speed X Time

The whole trip can be divided into two parts

Part 1 :- Speed = x mph  and time =  a hours

        ∴ Distance = x .a miles

Part 2 :- Speed = x -5mph  and time =  2 hours

        ∴ Distance =(x-5).2 = (2x -10)miles

Total distance = (x.a + 2x -10) miles
