Answer:
d = 7.5t
Explanation:
t = time
d= distance
you want to write an equation that compares time with distance.
in the question it says per hour whoch means 7.5 miles have been ran each hour. however we dont know how mmany hour lets say tom has ran. therefore, we use t instead. we got d to go behind the = sign because we are comparing. When we multiply 7.5t we are going to get the distance he ran, d.
hope this helps!
