Answers
ANSWER = 1.86 hr
Time taken by Noni = 3 .5 hr
Work done by
Noni in 1 hr = 1 / 3.5
Time taken by friend = 4 hr
Work done = 1/4
When they work
Together = 1 / 3.5 + 1 /4
= 4 + 3.5 / 14
= 0.536
Time taken = 1 / 0.536
= 1.86 hr
The time taken to finish work by Noni and Anton is 1.88 hours.
Step-by-step explanation:
Time taken by Nonni to paint the garage= 3 1÷2 hours= 7÷2 hours
= 3.5
Time taken by Anton to paint the garage= 4 hours
Work done by noni= 1÷time taken
=1÷3.5
Solution
Work done by Anton= 1÷4
Total work done by Noni and Anton= 1÷4+1÷3.5
= 0.25+ 0.28
= 0.53
Thus, time taken to finish work by Noni and Anton= 1÷0.53= 1.88 hours
Result:
Thus, the time taken to finish work by Noni and Anton is 1.88 hours.
