Sam, John, Matt, and Bob are going to drive to Florida. It is a 8 1/4 hour drive. Sam drove 1 1/3 hours. John drove 1 5/6 hours. Matt drove twice as long as John. How many hours did Bob drive if he drove the remaining time?

Step-by-step explanation:

total hours = 8 1/4= 33/4

Sam = 1 1/3 = 4/3

john=1 5/6 =11/6

matt= twice as long as john= 2(1 5/6)= 11/3

Bob= x

4/3+11/6+11/3 + x =33/4

11+22+8/6 + x =33/4

41/6 + x =33/4

x = 33/4 - 41/6

x= 99-82/12

x=17/12

x =1 5/12

therefore Bob drove 1 5/12.
