Question

Two buses leave a bus station and travel in opposite direction from the same standing point.if the speed of one is twice the other and they are 240km apart at the end of one hour. What is the speed of each km

Answer 1

V1 = Speed of 1st bus.
V2 = 2V1 = Speed of 2nd bus.

d1 + d2 = 240.
V1*t + 2V1*t = 240,
3V1*t = 240,
3V1*1 = 240, V1 = 80 km/h.

V2 = 2V1 = 2*80 = 160 km/h.

Answer 2

Is this correct

Answer 3
