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.
Answer:
It takes 3 minutes.
Explanation:
The distance between the two subways is 3 miles.
The train travels at an average speed of 60mph (miles per hour).

We have to convert hours to minutes and we do that by cancelling out the hours and replacing it with minutes.
There are 60 minutes in an hour so we use that, 1 hour/60 minutes and multiply it to the existing speed we have.
The result is 1 mile per minute.
We then multiply the miles by 3 since that is how much we want and we get 3 minutes.
