The person walked total 75.132 miles in 4 miles/hour speed.
It is the rate of change of distance with respect to time. Sometimes velocity is remained constant. Then termed as constant speed.
There are several equations developed that express the relationship between distance, velocity and time. One of such equation is
distance = speed x time
given, walking speed of the person, V= 4 miles/hour
time of walking by the person, t₁ = 1/5 hour
t₂ =3/4 hour
t₃= 5/6 hour
t₄= 17 hour
now, total distance walked by the person = D
from the equation of distance, velocity and time, we know
distance = velocity × time
here distance D = V×(t₁+t₂+t₃+t₄)
D = 4× (1/5+3/4+5/6+17)
Distance walked = 75.132 miles
