Together, Bob and Tom take 4 hours to get the yard work done. If Bob works alone, it takes him 6 hours. How long
would it take Tom, working alone, to do all of the yard work?
The answer is 12 and let me tell you how can you get to that conclussion:
The answer is 12 and let me tell you how can you get to that conclussion:Let X be the number of hrs Tom takes to do it
The answer is 12 and let me tell you how can you get to that conclussion:Let X be the number of hrs Tom takes to do itAdd their rates of working
The answer is 12 and let me tell you how can you get to that conclussion:Let X be the number of hrs Tom takes to do itAdd their rates of working( 1 yard ) / ( 6 hrs ) + ( 1 yard ) / ( X hrs ) = ( 1 yard ) / (4 hrs ) and then what you do is
The answer is 12 and let me tell you how can you get to that conclussion:Let X be the number of hrs Tom takes to do itAdd their rates of working( 1 yard ) / ( 6 hrs ) + ( 1 yard ) / ( X hrs ) = ( 1 yard ) / (4 hrs ) and then what you do is1/6 + 1/x = 1/4
The answer is 12 and let me tell you how can you get to that conclussion:Let X be the number of hrs Tom takes to do itAdd their rates of working( 1 yard ) / ( 6 hrs ) + ( 1 yard ) / ( X hrs ) = ( 1 yard ) / (4 hrs ) and then what you do is1/6 + 1/x = 1/4Remember to multiply both sides by 12x
The answer is 12 and let me tell you how can you get to that conclussion:Let X be the number of hrs Tom takes to do itAdd their rates of working( 1 yard ) / ( 6 hrs ) + ( 1 yard ) / ( X hrs ) = ( 1 yard ) / (4 hrs ) and then what you do is1/6 + 1/x = 1/4Remember to multiply both sides by 12xthen = 2x + 12 = 3x
