Answer:
The car travels 45 miles in one hour.
Step-by-step explanation:
Knowing that one hour is 60 minutes and that the car travels 0.75 miles every minute, you can multiply 60 and 0.75 which gives you 45 miles per hour meaning in one hour the car travels 45 miles.
x= 20
y = 60
y = 3x
6(3x) = 360
3x = 360/6
3x = 60
x = 20
y = 3*20
