MAth word problem
posted by Julie Anne .
lisa left home in a car that was traveling at the rate of 48 km/hr. she walked home at the rate of 6 km/hr. the round trip took 1.5 how far did lisa ride?

One of the best ways to do these is by using a "chart"
on the top: distance  rate  time
one the side: the two cases, in this problem: by car , walking
....... dist........rate....time
car ...48t ...... 48 ...... t
walk 6(1.5t) .. 6 ..... (1.5t)
So where does the equality come in ????
Ahhh, their distances are the same!
so solve
48t = 6(1.5t)
( I get t = 1/6 and
distance = 48(1/6) = 8 ) 
thank you reiny^_^
