You can put this solution on YOUR website! .While waiting for a train, alvin takes a bus ride at 60 kph to a certain point
and then take walks back leisurely at 10 kph. The bus takes 1/4 hour less than his walking.
How far does he walk and how long.
:
Let t = time he walked
then
(t-.25) = time rode; (changed 1/4 to .25)
:
Write a distance equation; dist = speed * time
:
riding dist = walking dist
60(t-.25) = 10t
60t - 15 = 10t
60t - 10t = 15
50t = 15
t =
t = .3 hrs, which is .3*60 = 18, min is time he walked
:
Find the dist
10 * .3 = 3 km he walked, (and rode)
:
:
Confirm our solutions by finding the dist he rode
(.3-.25) * 60 =
.05 * 60 = 3 km also
