Answer:
The two brothers working together will take 7.7 hours to dig the entire ditch.
Explanation:
Assuming T to be the total amount of time taken by both brothers working together, we can say
- 1/T ditch/hour to be the rate at which both brothers dig the ditch together
- 1/14 ditch/hour to be the rate at which the older brother digs the ditch
- 1/17 ditch/hour to be the rate at which the younger brother digs the ditch
So the rate at which both brothers dig the ditch can be calculated by the equation,
1/T = 1/14 + 1/17
T = 238/31 = 7.7 (rounded off to the nearest tenth)
Answer:
13.8 N
Explanation:
Pressure on the one end of the hydraulic system = Pressure on the other end
Pressure = Force / Area where Force is in Newton, area is in m²
so Force of one end (F1) / area of that end = force of the other end (F2) / area of that end
3112 / ( 707 /10000) in m² = F2 / ( 3.14 / 10000) in m²
cross multiply
44016.97 × 0.000314 = 13.82 N
