50 minutes 18seconds as percent of 2 hours

42%

Step-by-step explanation:

The best way to start is to work with common units. In this case, seconds are best.

1 minute = 60 seconds

50 minutes = (60 x 50) = 3000 seconds

3000 + 18 = 3018 seconds

This is our first variable.

1 hour = 3600 seconds(if you change to mins then to seconds is fine too)

2 hours = (3600 x 2) = 7200 seconds

From the question, we can tell;

2 hours = 100%

So we need to find out, 50 minutes 18 seconds = x%

( x is our unknown)

7200 seconds = 100%

3018 seconds = ((3018 x 100) ÷ 7200)

41.916 %

Let's round of to the nearest 1

42% (since 9 is higher than 5, we add 1 to the number before it)
