Melanie swarm for 142 minutes during her first week of vacation. In her two weeks of vacation she swam for a total of 347 minutes. How many more minutes did she swim for in the second week than in the first week

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.
