Answer:
3 hours and 45 minutes
Step-by-step explanation:
let's assume the tank has a volume of x liters.
let's assume the speed of filling it is x/6 liters per hour for A and x/10 liters per hour for B.
the formula to calculate the time is:
time = volume / speed
If the pumps work together, the total speed is x/6 + x/10, which is 16/60 x
So the time this takes is:
time = x / (16/60 x) = 60/16 hours = 3.75 hours = 3 hours and 45 minutes.
Answer:
these are the answers you need and you'll need it anyways yw
1) 3 x 4 = 12 + 3 = 15/10= 1.5
1.5/4 =<em> 3/8 drink mix for one drink</em>
2) 22/8
22/3=7.3
<em>so 7 cups of drinks </em>
