Answer:
60 miles
Step-by-step explanation:
She travels 40 miles in one hour. So in the first hour, she's driven 40 miles. For the last 0.5 hours, she drives half of what she drove in the first hour, which would be 40/2 = 20. Combine these two numbers to get the total miles driven in 1.5 hours.
40 + 20 = 60
60 miles.
Hope this helps.
