Answer:
Step-by-step explanation:
<u>The filling speed is 30 hours or:</u>
<u>The draining speed is 34 hours or: </u>
<u>If both lines are open simultaneously, the filling speed is:</u>
- 1/30 - 1/34 =
- 17/510 - 15/ 510 =
- 2/510 =
- 1/255 in an hour
<u>If the tank is 1/5 full, then we need to fill the 4/5 of level and it will take:</u>
- 4/5 : 1/255 =
- 4/5 *255 =
- 204 hours
Answer:
x = 5
Step-by-step explanation:
12x - 6 + 6 = 54 + 6
12x = 60
