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)
