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
