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
