Distance time graphs
1

Sketch a graph that shows the height of a ball being thrown vertically into the air. Time should be on the horizontal axis, and height should be on the vertical axis.

2

A man is driving along a highway in a car at a constant speed. After a period of time, he decreases his speed because of road work. Sketch a graph that represents the relationship between distance travelled and time taken.

3

Tina is cycling to the bus stop, but halfway there she gets a flat tire and has to push her bike the rest of the way. Upon reaching the bus stop, she has a short wait for the bus and then catches the bus to her final destination. Sketch a graph that represents the relationship between distance travelled and time taken.
