Question

Can someone give me a step by step answer on how they figured this out so I understand it PLEASE???

i need to figure out How many miles per hour the train is going

Answer 1

25 mph

Explanation:

The slope of the line gives the rate of change (speed) of the train

From the graph note that after 6 hours the distance travelled is 150 miles

Thus slope =
`(150)/(6)` = 25

The train is travelling at 25 mph
