Question

Show an equation and a solution for the problem. Crane A can unload a ship in 10 hours and crane B can unload it in 14 hours. How long will it take the two cranes to unload the ship working together? Round to the nearest tenth.

Answer 1

my last question lol..

Answer 2

i believe the equation is\[{1 \over t} ={ 1 \over 10} + {1 \over 14}\] as time is inversely proportional to the number of cranes that work, but i may be wrong (probably a silly mistake at this time of the day maybe possible :P )

Answer 3

did u verify if it is correct?

Answer 4

The answer is correct, but I wouldn't have done it that way :P

Answer 5

thanks guys lol
