Question 1083145: A person has a hrs. at his disposal. Determine distance he may ride in b miles per hr., and walk at c miles per hr., to get back in time.
Distance = rate * time.
Unsure how to continue. Non-homework. Thanks. Answer by Boreal(15235) (Show Source):
You can put this solution on YOUR website! the amount of time will be t and a-t, both in hours. They add to a.
bt=distance on bicycle
c(a-t)=ca-ct=distance walking
ca-ct=bt if walking and riding cover the same distance
ca=bt+ct
ca=t(b+c)
t=ca/(b+c)
bicycle d=bca/(b+c)
walking distance is c(a-t)=ca-ct.There are many other ways to practice solving for any one of these variables in terms of the others.
