Question

Isa finished 30% of his homework in 27 minutes. How many more minutes will it take Isa to complete his homework, assuming that he works at the same pace?

Answer 1

% completed = 30%
Time taken = 27 minutes
Remaining % completion = 70%

Time to be taken for the remaining work
70/30 × 27= 63
  = 63 min

Total time taken
63 +27 = 90

 Answer = 90 minutes
