suppose it takes matt 3 hours to plant a flower in garden when working alone. it take vanessa 6 hours to plant flowers in teh same garden when working alone. if matt and vanessa work together to pant fowers how long will it take?

Solution

Given that

Matt plant a flower in garden in 3 hours

  Matt plant a flower in garden in 1 hour = 1/3

Vanessa plant a flower in same garden in 6 hours

Vanessa plant a flower in same garden in 1 hour = 1/6

Hence,

Matt and Vanessa work together to pant fowers in 1 hour = 1/3 + 1/6

= 2+1 / 6

= 3 / 6

= 1 / 2

  Matt and Vanessa work together to pant fowers = 2 hours
