Diane is going home to visit her family for the holiday. She needs to be sure that she will be back at her home on time. She lives in New York, which is 90 miles away. Her car gets 19 miles per gallon and she can drive 55 miles per hour. How many gallons of gas should she be sure to have so that she has enough for her around trip?



Answer :

Answer:

Diane needs to travel a total of 180 miles for the round trip. Her car gets 19 miles per gallon. To find out how many gallons of gas she needs:

1. Calculate the total distance: 2 times 90 miles = 180 miles.

2. Divide the total distance by her car's miles per gallon: 180 div 19 approx 9.47 gallons.

So, Diane should make sure she has at least 10 gallons of gas for her round trip.
