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?

Respuesta :

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

[tex]360=70(3)+x(3)[/tex]

[tex]360=210+3x[/tex]

[tex]3x=150[/tex]

[tex]x=50[/tex]

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