To solve rate word problems, knowledge of solving systems of
equations is necessary. Rate word problems include problems
dealing with rates, distances, time and wind or water current.
Other types of word problems using systems of equations include
money word problems and age word problems. Here we have another
word problem related to linear equations. I can ride my bike to
work in an hour and a half. If I drive 40mph faster than I bike
and it takes me 30 minutes to drive the same distance. How far
is it to work? Okay so here we have a couple of rates, we have
times. Distance, rate time problem hopefully that formula sounds
somewhat familiar. Distance equals rate times time, okay so in
this particular problem we're actually dealing with two
scenarios. We're dealing with biking and we're dealing with
driving. What comes in handy for people who sort of organize
their thoughts is to make a table. Okay so what we have is
distance, rate and time. Bike and drive, okay so in both
instances I am going from my house to
