To find: Whether the teams are capable of hearing each other anywhere on the field.

Answer to Problem 49PPS
The teams are not capable of hearing each other anywhere on the field.
Explanation of Solution
Given:
The equation is
The range of walkie-talkie is
Calculation:
Rewrite the given equation in the standard form.
The field has an ellipse form and the major and minor axes of the ellipse are as follows.
The major and minor axes are more than the range of the walkie-talkie that is
Therefore, the teams are not capable of hearing each other anywhere on the field.
