Question

A train traveled 325 miles in 5 hours. What was the train's average rate of speed in miles per hour?

Answer 1

`v_a=65" " ("miles")/("hour")`

Explanation:

`v_a=(Delta s)/(Delta t)`
`v_a:"average speed of train"`
`Delta s:"Total distance"`
`Delta t:"Elapsed time"`
`v_a=325/5`
`v_a=65" " ("miles")/("hour")`
