2. it would descend 4.64 or 5f rounded in 8 minutes (8/0.125)
Answer:
4.45 feet p/m
35.56 feet per 8 minutes
Step-by-step explanation:
20 / (60x4.5) = 60 seconds = ( 1 x 4.5 minutes)
20/270=0.0740740741 1 = multiplier of feet/seconds
60 x 0.0740740741 1 =4.44444445 feet in one minute = 4.45feet
60 x 8 = 480 seconds (1 x 8 minutes)
480 x 0.0740740741 1 =35.5555556 feet
= 35.56feet in 8 minutes
