Respuesta :

50 yards per min
? feet per sec

Convert min to sec:-

1 min = 60 sec

Convert 50 yards to feet:

1 yard = 3 feet
3 × 50 = 150
50 yards = 150 feet

150 feet per 60 seconds

150 ÷ 60 = 2.5

2.5 feet per second

50 yards per min = 150 feet per 60 sec = 2.5 feet per sec
AL2006

         (50 yards/minute) x (3 feet/yard) x (1 minute / 60 seconds)

     =  (50 · 3 · 1 / 60) (yard-feet-minute) / (minute-yard-second)

     =       2.5 feet/second .
