Hey guys I need some help with this problem

I think the answer is 1hr and 32mins.

Step-by-step explanation:

24×3=72. 72-40=32. So I think its 1hr and 32mins.

1 hour and 48 minutes

Step-by-step explanation:

Convert the inches shown to miles. They give you the conversion (1 inch=24miles) and so you convert the 3 inches to 72 miles(3 inches×24 miles). To then calculate the time, you divide 40 miles by 1hr(60 minutes) because you want to find out how long it takes her to drive 1 mile. you get 1.5, so you multiply 1.5(time per mile) and 72(total miles) to get 108, which is one hour and  48 minutes
