Question

2. The speed-time graph (left) represents a cheetah chasing a

gazelle.
a) Does the top graph represent the cheetah or the
gazelle?
b) Calculate the distance covered by the cheetah
within 16 seconds.
c) Calculate the distance covered by the gazelle
within 16 seconds.
d) What is the difference in (m) between the gazelle
and the cheetah?

Answer 1

a) The graph at the top is the cheetah

b) The distance of Cheetah is 480 m

c) The distance of Gazelle is 320 m

d) The difference is 160 m

What does the speed time graph mean?

A speed-time graph, also known as a velocity-time graph, illustrates the relationship between an object's speed (or velocity) and time. In such a graph, the horizontal axis represents time, and the vertical axis represents speed or velocity.

For Cheetah;

Distance = speed * time

= 30 m/s * 16 s

= 480 m

For Gazelle;

Distance = speed * time

=20 m/s * 16s

= 320 m

Difference in distance = 480 m - 320 m

= 160 m
