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

write an equation for “d” , the distance traveled by the train after “h” hours

To complete the table you will want to first write the equation.

You will need to find out what is happening to the time (number of hours) in order to get the distance.

You will use the numbers 3 and 120 to figure this out.

3 is multipled by 40. This means when you know the number of hours, you just multiply by 40 to find the distance.

When you know the distance, you divide by 40 to find the number of hours.

2 x 40 = 80
8 x 40 = 320
200/40 = 5

The equation is d = 40h.
