Dumi travels 62 miles each day from his house to school.
he walks to the bus stop at 4 miles per hour
He rides the rest of the way by bus which averages 40 miles per hour.
The entire trip takes 2 hours.
How much time does he spend walking and how much time does he spend on the bus
:
Let b = time spent on the bus
"Entire trip takes 2 hrs," therefore:
(2-b) = time spent walking
:
Write a distance equation, dist = speed * time
:
Bus dist + walk dist = 62 mi
40b + 4(2-b) = 62
:
Find b, (time spent on the bus) then time walking
