Question

They traveled 200 kilometers in total, and they biked 40 kilometers more than they were bussed. how many kilometers did they travele by bike

Answer 1

Let the distance travelled by bus be x and the distance travelled by bike be (x+40)

So...

x + (x+40) = 200

2 x = 160

1 x = 80

200 - 80 = 120km by bike.
