Since 1/2 is equal to a half, you divide 50 and 40 by 2 and you'll get 25 and 20 and then you subtract 25 and 20 and you get 5 which is the answer!

Melanie swarm for 142 minutes during her first week of vacation. In her two weeks of vacation she swam for a total of 347 minute
Soloha48 [4]

Answer: Melanie swam 63 minutes more in second week.

Step-by-step explanation:

Given ,  Time taken by Melanie in first week to swim = 142 minutes

Combined  time taken by her in first two weeks in swimming = 347 minutes

Now , time taken by her in second week =  (Combined  time  of first two week) - (Time taken in first week)

= 347-142 minutes

=  205 minutes

Clearly , 205 > 142 i.e. She swam more in second week than first week./

Difference i= 205-142 = 63

Therefore, Melanie swam 63 minutes more in second week.
