Respuesta :

x = 650 + 60t

The cheetah must arrive at the same place at the same time:

x = 90t

650 + 60t = 90t

30t = 650

t = 650/30 ≅ 21.7 s

It takes the cheetah a little more than 20 s running at 90 ft/s to reach the moving antelope, so assuming the antelope can maintain its speed of 60, it is safe.

Find the required table attached

Since the speed of the Cheetah is constant, this means that the speed must be the same all through in the table.

To get the unknown time and distance, we will have to use the formula below:

  • Speed = Distance/Time = k
  • When distance = 120m, time = 4secs

Speed = 120/4 = k

Speed = 30m/s = k

We are to get the distance when the time is 25secs

Speed = Distance/Time

30 = d₂/25

d₂ = 30 × 25

d₂ = 750 m

To get the time in the third column

Time = Distance/Speed

t₃ = 270/30

t₃ = 9seconds
