Answer to Problem 34E
No
Explanation of Solution
Given:
Speed of cheetah = 90 feet per second
Speed of antelope = 60 feet per second
Initial distance between Cheetah and antelope = 650 feet
Formula Used:
Let the time taken by cheetah to catch up to the antelope be x seconds.
The distance travelled by Cheetah in x seconds
The distance travelled by Antelope in x seconds
As, in x seconds Cheetah catches up to antelope, so,
But it is known that cheetah can run at its top speed only for 20 seconds and in the given case it requires 21.67 seconds for cheetah to catch up to antelope, so it can be said that the antelope will be safe.
Conclusion:
No, if the distance between them is 650 feet, then the antelope will be safe.
