Hello,

oksano4ka [1.4K]

It took him 9.92 hours to complete the journey.

Step-by-step explanation:

Given,

Distance traveled = 50 miles

Distance traveled on horse = $\frac{50}{2}=25\ miles$

Distance traveled on foot = 25 miles

Speed while riding = 9 miles per hour

Distance = Speed * Time

Time while riding = $\frac{Distance}{Speed}$

Time while riding = $\frac{25}{9}=2.78\ hours$

Speed while waling = 3.5 miles

Time = $\frac{25}{3.5}=7.14\ hours$

Total time = 2.78+7.14 = 9.92 hours

It took him 9.92 hours to complete the journey.
