Formula Used:
Distance=speed×time
Let the time taken by cheetah to catch up to the antelope be t seconds.
The distance travelled by Cheetah in t seconds =90x
The distance travelled by Antelope in t seconds =60x
As, in t seconds Cheetah catches up to antelope, so,
90x60x=120
30x=120
x=12030
x=4
Conclusion:
Thus, the time taken by cheetah to catch up to the antelope is 4 seconds.

Result:
We used the equation dc=da+120 to represent the distances covered by the cheetah and the antelope. By solving this equation, we found that the cheetah would catch up to the antelope after 4 seconds.
Solution:
Let's assume that the cheetah catches up to the antelope after time t seconds. During this time, the cheetah will have covered a distance equal to its velocity multiplied by the time taken, and the antelope will have covered a distance equal to its velocity multiplied by the time taken.
The distance covered by the cheetah can be expressed as dc=90t feet, and the distance covered by the antelope can be expressed as da=60t feet.
Given that the cheetah is initially 120 feet behind the antelope, we can set up the equation:
dc=da+120
Substituting the expressions for dc and da:
90t=60t+120
Now, we can solve this equation for t:
90t60t=120
30t=120
t=12030
t=4 seconds
Therefore, it will take the cheetah 4 seconds to catch up to the antelope.

Given:
t=dv
where:
- t is the time taken,
- d is the distance between the cheetah and the antelope, and
- v is the relative velocity of the cheetah with respect to the antelope.
Given that the cheetah is 120 feet behind the antelope, we have d=120 feet. The relative velocity of the cheetah with respect to the antelope is the difference between their speeds, so v=9060=30 feet per second.
Plugging these values into the equation, we get:
t=12030=4 seconds.
Therefore, it will take the cheetah 4 seconds to catch up to the antelope.

Step 1:
The distance traveled by the cheetah in t seconds can be calculated by multiplying its speed (in feet per second) by the time:
Distance traveled by the cheetah=Speed of the cheetah×t
Similarly, the distance traveled by the antelope in t seconds is given by:
Distance traveled by the antelope=Speed of the antelope×t
Step 2:
Given that the cheetah is initially 120 feet behind the antelope, we can set up the following equation:
Distance traveled by the cheetah=Distance traveled by the antelope+Initialdistancebetweenthem
90t=60t+120
Simplifying the equation, we get:
30t=120
Step 3:
To solve for t, we divide both sides of the equation by 30:
t=12030
Simplifying further:
t=4 seconds
Therefore, it will take the cheetah 4 seconds to catch up to the antelope.
