Question

Joe left the hospital at the same time as Eugene. They drove in opposite directions. Eugene drove at a speed of 70 km/h. After three hours they were 360 km apart. How fast did joe drive?

Answer 1

If Joe and Eugene are travelling in opposite directions, their total distance is 360 km.

Eugene's speed = 70 km/hour

Let Joe's speed be = x

They each travel for 3 hours, so time = 3 hours

Distance = speed * time

`360=70(3)+x(3)`

`360=210+3x`

`3x=150`

`x=50`

Hence, Joe's speed is 50 km per hour.
