Answer:
d = 45 * t
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
