Answer 2

Total number of horses used = 16

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 = }(176)/(2)=88miles`

They changed horses every 11 miles.

`\texttt{Number of horses used by each pony express rider = }(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
