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

Answer:

21 miles

Step-by-step explanation:

Jeff drove $=\dfrac{1}{2}$ of the trip

Jason Joe drove $=\dfrac{1}{4}$ of the trip

Together Jeff and Jason Joe drove $=\dfrac{1}{2}+\dfrac{1}{4}=\dfrac{2}{4}+\dfrac{1}{4}=\dfrac{3}{4}$ of the trip

All trip $=1$

Remaining trip $=1-\dfrac{3}{4}=\dfrac{4}{4}-\dfrac{3}{4}=\dfrac{1}{4}$

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

Susan drove = Sharon drove $=\dfrac{1}{4}:2=\dfrac{1}{4}\cdot \dfrac{1}{2}=\dfrac{1}{8}$ of the trip.

The entire trip was 168 miles, then

Sharon drove $=\dfrac{1}{8}\cdot 168=21\ miles$
