Question

3 hours 38 minutes 13 second + 4 hours 23 minutes 28 second + 8 hours 11 minutes 27 second​

Answer 1

Step-by-step explanation:

3 hours 38 minutes 13 second = [3hr × 3600s+{38min × 60s+(13s)}] = 13093 seconds.

4 hours 23 minutes 28 second = [4 hr × 3600s + {23min × 60s + (28s)}] = 15808 seconds.

8 hours 11 minutes 27 seconds = [8 hr × 3600s + {11min × 60s + (27s)}] = 29487 seconds.

Thus, 13093s + 15808s + 29487s = 58388 seconds.

That is equal to 16.2188 hrs or 16 hours 13 minutes 8 seconds
