Question 815519: a videotape plays 6.72 ft per minute for 2 hours at standard speed. It plays for 6 hours at extended long play speed. What is the rate of the tape at the slower speed? Answer by TimothyLamb(4379) (Show Source):
You can put this solution on YOUR website! r = d / t
d = r * t
---
d = 6.72 ft/min * ( 2 hr * 60 min/hr )
d = 806.4 ft of tape
---
at the slower speed:
r = d / t
r = 806.4 ft / ( 6 hr * 60 min/hr )
---
Answer:
r = 2.24 ft/min
