Could anyone help me with this question.

Andrew drove his truck 100 miles, rounded to the nearest 10 miles, and used 10 gallons of gasoline, rounded to the nearest gallon. The actual number of miles per gallon that Tom’s truck got on this vacation trip must have been between

100 miles rounded t nearest 10 miles which means Andrew drove his truck in between 95 -104 miles

similarly for fuel the actual usage will be between 9.5-10.4

Now, to get actual number of miles per gallon (Mileage) we have 2 options

1. when the mileage is maximum i.e maximum miles divided by minimum number of gallons = 104/ 9.5 =10.9 ( approx)

2. When the mileage is minimum i.e when the minimum miles divided by maximum number of gallons = 95/10.4= 9.1( approx)
