Problema Solution

you hike along the Appalation Trail at 3 miles pr hour.You stop for one hour for lunch. You want to walk at least 18 miles. How many hours should you expect to stay on the trail?

Answer provided by our tutors

Speed = 3 miles per hour 

time for lunch = 1 hour 

Total distance = 18 miles 

let time for walk = x hours 

using 

Speed = Distance / Time 

or Time = Distance / Speed 

or x = 18 miles / 3 miles per hour 

or  x =  6 hours 

Total time = time to walk + time for lunch 

Total time on trail = 6 + 1 = 7 hours  (answer)
