two miles from the bus stop if we were to graph the buses path well left the

00:29

station at zero minutes and with zero miles from the station which makes the

00:33

point right here in zero, zero well Jimmy's house is two miles from the

00:36

station and it took the bus four minutes to get to Jimmy's house and that makes [Bus travels to Jimmy's house on a graph]

00:40

point right here 2, 4... Well how fast did the bus

00:44

drive from the station to Jimmy's well yeah it took him four minutes but how [Students playing on the bus]

00:48

fast was he going to find out we use the formula for slope and plug in our

00:52

coordinates like this so now we know the bus drives at a constant rate of two

00:57

minutes per mile so that's 30 miles per hour on a residential street well wheels

in the bus are no longer round and round... well yes this buys you a few more

minutes before the bus makes your next stop and you can make some eggs for [Girl brushing her teeth]
