Answer to Problem 7MPS
Total time taken by me and my friend will be
Explanation of Solution
Given information:
I can weed garden in 90 minutes
My friend can weed garden in 20 minutes more than me.
My friend takes 20 minutes more than me:
Time taken by my friend= My time+20 minute
Time taken by my friend=90+20=110 minutes.
Work done by me in one minute =
Work done by my friend in one minute =
Let total time taken be
Total time taken by me and my friend will be
