Question

Draw aspeed v aganist time graph by guessing of the values of your trip to school this morning.show how this graph can be used to determine distance.

Answer 1

Do your own graph.
time on the x axis
speed on the y axis

t = 0 at start
t =T at end
speed varies with time but starts at 0 at t =0 and ends at 0 at school
now look at a little rectangle from t to t+ a second or two
the area under that rectangle is the distance (speed * time) you went from t to t + a second or two
so the total area under that v versus t graph line is the distance from your house to school, the sum of all those little distance rectangles.
There is a name for that, integral calculus.
