A cheetah can run at a maximum speed of 102 km/h, and a gazelle can run at a maximum speed of 73.4 km/h. If both animals are running at full speed, with the gazelle 59.1 m ahead, how long will it take before the cheetah catches its prey?

Answer in units of meters.

Answer :

Final answer:

The cheetah will take approximately 7.45 seconds to catch the gazelle when they are running at full speed.

Explanation:

To find the time it takes for the cheetah to catch the gazelle, we need to determine how long it would take for the cheetah to cover a distance of 59.1m at its maximum speed of 102km/h. First, we convert the speeds to the same units by dividing the cheetah's speed by 3.6. This gives us the speed of the cheetah as 28.33 m/s and the speed of the gazelle as 20.39 m/s. Next, we can use the equation:



Time = Distance / Relative Speed



Plugging in the values, we get:



Time = 59.1m / (28.33 m/s - 20.39 m/s)



Simplifying further:



Time = 59.1m / 7.94 m/s



Calculating the final value, we find that it will take approximately 7.45 seconds for the cheetah to catch the gazelle.
