Answer:

76.4 m

Step-by-step explanation:

The race track has two straights and two semi circles.

Each straight is 80m

total perimeter for the straights is 80 * 2 = 160m

two semi circles which creates a full circle

perimeter of a full circle = \pi d

NB : (d) is the diameter

therefore we can find the value of the diameter

400 = 160 + \pi d

400- 160 = \pid

240 = \pid

d = 240/\pi

d = 76.394.....

<u>d = 76.4 m</u>

a person running down a field to score a touchdown

DONT HAVE ENOUGH INFORMATION

the two graphs are proportional to time and

a dog jumping at a constant speed for 20min and
