Question

is it P=rw 

Answer 1

"A scuba diver is diving at a depth of 75ft and is beginning to ascend at a rate of 10 feet per minute when will her depth be 5 feet?"

 

D = RT

T = D/R

T = (75ft -5 ft)/(10 ft/min)

T = (70 ft) / (10 ft/min)

T = 7 minutes

Answer 2

time=distance/speed=5/10=0.5 minute =30 seconds
