The Zalinsky family can drive the 220 miles to their cabin in 4 hours at 55 miles per hour. Son Jeff claims that they could save half an hour if they drove 65 miles per hour, the speed limit. How long will it take the family if they drive 65 miles per hour? My solution is 3 hour and 38 min. But in the math book answer is 3 hours and 23 min. Please help me with right solution, thank you so much!!!!
