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.

Keywords: speed, distance
