Answer:
2/3 hours or 40 mins.
Step-by-step explanation:
No. of trees planted by David = 11
No. of hours worked by David to plant 11 trees = 7 1/3 hours = (7*3 + 1) /3 = 22/3
It takes him about the same amount of time to plant each tree
let time taken to plan 1 tree be x
then time taken to plan 1*11 tree = 11*x
But, given that total time taken is 22/3 hours
thus,
11x = 22/3 hours
x = 22/(3 *11) = 2/3
Thus, it took 2/3 hours to plant each tree.
As 1 hour has 60 minutes
Time taken in minutes to plant 1 tree = 2/3 *60 mins = 40 mins
