Answer:
x=5 miles
Step-by-step explanation:
first you have to get his constant speed or his rate
rate = time / distance
so in this case 27/3 which equals 9,
1 mile = 9 minutes
then, you would set up your equation
9 minutes = 1 mile
45 minutes = x miles
cross multiply , 45 * 1= 45 , then divide by 9
x = 5 miles
