Question

Two buses leave a bus station and travel in opposite directions from that same starting point. If the speed of one is twice the speed of the other and they are 240km apart at the end of one hour, what is the speed of each bus?

Answer 1

80 km/hr and 160 km/hr

Step-by-step explanation:

assuming answer can be in km/hr:

let x = rate of 1st bus

2x = rate of second bus

distance = rate x time

2x(1 hr) + x(1 hr) = 240 km

3x = 240 km

x = 240/3 = 80 km/hr

2x = 160 km/hr
