First we will calculate rate of work of rosa and amy.
work done by rosa in time t=t*1/7
Work done by Amy and rosa=t(1/7+1/4.2)
t/7+t/a=t/4.2
t=10.5 hr
Always keep remember those formula or logic belowWork rate × Time to finish the job = 1 job done
Work rate = (1 job done) / (Time to finish the job)
Time of doing the job = (1 job done) / (Work rate)
Complete question :
Ruben put an empty cup underneath a leaking faucet. After 1 1\2 hours, Ruben collected 1/4 cup of water. What is the rate, in cups per hour, at which the water is leaking from the faucet?
Answer:
1/6 cups per hour
Step-by-step explanation:
Given that :
Time = 1 1/2 hours = 1.5 hours
Cups of water collected = 1/4 cups
Rate in cups per hour :
Cups collected / time
1/4 ÷ 1 1/2
1/4 ÷ 3/2
1/4 * 2/3
= 2/12
= 1/6 cups per hour
