Answer:
Time, t = 141 seconds
Explanation:
Given that,
Distance between the class and the person, d = 282 m
Speed of the person, v = 2 m/s
We need to find the time taken by the person to get to your class. Let the time taken is t. The speed of the person is given by :
t = 141 seconds
So, the time taken by the person to get to your class is 141 seconds. Hence, this is the required solution.
