Answer 2

Step-by-step explanation:

Time taken to complete 1st round= 3/4

Time taken to complete 2nd round= 1 1/2

Time taken to complete 3rd round= ?

1st round + 2nd round + x = 4 minute

3/4 + 1 1/2 + x = 4 minute

3/4 + 3/2 + x = 4 min

3+6/4 + x = 4 min

9/4 + x = 4 min

x = 4 - 4/9

x = 36 - 4/9

x = 32/9

Therefore, the time taken to complete the third round = 32/9
