Question

Friends go on a trip. Jeff drove 1/2 of the trip and Jason Joe 1/4 of the trip.Susan and Sharon divided the rest of the drive equally.If the entire trip was 168 miles, how many miles did Sharon Drive?

Answer 1

21 miles

Explanation:

Jeff drove
`=(1)/(2)` of the trip

Jason Joe drove
`=(1)/(4)` of the trip

Together Jeff and Jason Joe drove
`=(1)/(2)+(1)/(4)=(2)/(4)+(1)/(4)=(3)/(4)` of the trip

All trip
`=1`

Remaining trip
`=1-(3)/(4)=(4)/(4)-(3)/(4)=(1)/(4)`

Susan and Sharon divided the rest of the drive equally, so

Susan drove = Sharon drove
`=(1)/(4):2=(1)/(4)\cdot (1)/(2)=(1)/(8)` of the trip.

The entire trip was 168 miles, then

Sharon drove
`=(1)/(8)\cdot 168=21\ miles`
