Hello!
Judging by the question you have provided I came to the conclusion that to find the speed at which the student runes in feet per minutes you need to first start off by converting the distance, 50 yards, to feet.
To do this you need to use the equation 3x=y. X being yards Y being feet.
Your equation should look something like this, 3(50 Yards)= Feet, and your answer should be 150 feet.
The next step is to see the distance the student runs in feet per second. To do this you need to divide the 150 feet by 6.1 seconds.
Your answer should be 26.23 feet per second.
Lastly you now need to see the distance the student would run if they ran for a minute.
To do this you need to multiply the feet per second by 60 (one minute).
Your answer should be ~1574 feet per minute.
Hope this helped!
