Imayumi hikes 3 miles in 2 hours. edwin hikes 4 miles in
3 hours. who takes more time to complete a 12-mile hiking
trail? how much more time?

Mayumi hikes 3 miles in 2 hours and Edwin hikes 4 miles in 3 hours.

12 miles = 3x ————— (2 hours • X)

12/3=x—————(2x)

4=x—————(2(4))= 8hours

Mayumi walked 12 miles in 8 hours

12miles=4x————(3hours • X)

12/4=X————-(3x)

3=X————-(3(3))= 9 hours

It takes Edwin 9 hours to hike 12 miles, while it only takes mayumi 8 hours

a) Edwin takes longer to hike 12 miles

b) it takes him 1 hour longer to hike the 12 miles

The correct answer is .44
