If jake can complete a job in 1 hour 30 minutes and his friend harry can complete the same job in half the time, how long will it take to complete the job if they work together?

if they work together, it will take them 0.5 hours or 30 minutes

Step-by-step explanation:

jake can complete a job in 1 hour 30 minutes or 1.5 hours. This means that his unit rate is 1/1.5

his friend Harry can complete the same job in half the time. This means that Harry can complete the same job in 0.75 hours. His unit rate of working would be 1/0.75.

Since both of them work simultaneously at their individual rates, then, Their unit rates are additive. Assuming by working together, it took them t hours to finish the work. This means that their combined unit rate would be 1/t. Therefore,

1/1.5 + 1/0.75 = 1/t

1/t = 2

2t = 1

t = 1/2 = 0.5 hours or 30 minutes

i'm not sure what you mean but in todays world there is a lot of women that are the bread winners in the family. there is a lot more single mothers now that are going back to get an education which is boosting the economy. i believe there has been a boost in the economy due to women the cosmetic industry is boosting, chemist, the sky is becoming the limit for women in todays economy. most women are also putting off having kids just to make sure they have a education. i don't know how these two relate though to scriptures because it's not the way the lord wanted it. the man is suppose to be the bread winner and due to social media and the easy access we have there is a lot of cheating going on.
