Question

It takes terrel 69 minutes to weed his garden if he does it every 2 weeks, while his wife can get it done in 49 minutes. How long would it take them working together? Round to the nearest tenth of a minute

Answer 1

Answer: 28.7 minutes

Explanation:

Terrel:
`(1)/(69)` of job per minute

Wife:
`(1)/(49)` of job per minute

Together:
`(1)/(x)` of job per minute

Terrel + Wife = Together

`(1)/(69)+(1)/(49)=(1)/(x)`

`(1)/(69)(69*49*x)+(1)/(49)(69*49*x)=(1)/(x)(69*49*x)`

49x + 69x = 69 * 49

118x = 3381

x = 28.7
