Question

A freight train is traveling at a constant speed. The table below shows how far the train travels after different amounts of time.

Time

(in hours)

Distance

(in miles)

3 120
5 200
8 320
Which of the following is the correct equation for d, the distance traveled by the train, after h hours?


d=40h


d=60h


d=80h


d=120h

Answer 1

the correct question would be d=40h simple

Answer 2

The correct equation would be d=40h.

You can test this out by substituting the number of hours into h to find d.
Ex.

h=3 hours

d=40h
d=40(3)
d=120 (this matches up with the distance given in the table for 3 hours

Hope this helps!! :)
