anonymous · Answer

1 - 1/4 - 5/8 = 1/8
24 x 1/8 = 3 miles left

anonymous · Answer

$$\frac{3}{8}24=9 \text{ miles} $$

anonymous · Answer

can u tell me how you got 3/8

anonymous · Answer

"by lunchtime, they rode 5/8 of the total distance." is the key.  8/8 is the whole distance of 24.  They had traveled 5/8 at lunch time.  That leaves 8/8 - 5/8 = 3/8 left to ride.
