atroni [7]

Answer:

Total number of horses used = 16

Step-by-step explanation:

Two pony express riders each rode part of a 176 mile trip. Each rider rode the same number of miles.

\texttt{Total mile rode by each pony express rider = }\frac{176}{2}=88miles

They changed horses every 11 miles.

\texttt{Number of horses used by each pony express rider = }\frac{88}{11}=8

Total number of horses = Number of horses used by each pony express rider x Number of pony express rider

Total number of horses used = 8 x 2 = 16

Total number of horses used = 16
