Question

two trucks leave a house at the same time.one travels average speed of 58 west.The other is east average speed of 46 miles per hour. How many hours will the two trucks be 208 miles apart?

Answer 1

The 2 trucks left the house the same time.

average speed of the first one = 58 miles per hour west

average speed of the second one = 46 miles per hour east

Let us use a diagram to illustrate their movement

Therefore,

`\begin{gathered} \text{speed}=\frac{dis\tan ce}{\text{time}} \\ \text{distance}=speed\text{ }* time(t) \\ 208=58t+46t \\ 208=104t \\ t=(208)/(104) \\ t=2\text{ hours} \end{gathered}`

Therefore, the trucks will be 2 hours after
