Step-by-step explanation:
y-x=4

It's asking you to work out how many minutes it will take to drive to a school if you're driving at a speed of 35 miles per hour (mph).
But there's a problem with the question because it doesn't tell you how far away the school is.
But this is how you are supposed to do it:
Distance ÷ 35 = answer (in hours)
Answer (in hours) × 60 = Final answer (in minutes).
It's like this because time = distance ÷ speed, and the question asks for the answer in minutes, but the unit is in miles per hour, so you multiply by 60 to get the answer in minutes.
Hope I helped :)
