A train travels at 45 miles per hour. Write and equation that represents the distance, d, that the train will travel, in t hours.

d = 45 * t

Step-by-step explanation:

Step 1: Ok so for a. we can just need to build a equation representing the space the practice travels in t hours:

We can also recognize that it travels 45 mph, in order that is representing by 45 (t).

d is the distance. So the equation is d = 45 (t)

Step 2: For phase b. we change 2.5 with t a the equation. Then we solve it

d = 45 (2.5)

45 * 2.5 = 112.5

d = 45 * t

Step-by-step explanation:

We know the equation as dert

distance equals rate * time

d = 45 * t
