Express the rate 50 yards per minute in feet per second

(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.

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
