Question

Express in seconds: 3 hr 5 min 7 sec.

Answer 1

Answer:

• First we have to convert 5 minutes into seconds

$5 \times 60 = 300 \: seconds$

• Then we have to convert 3 hrs into minutes and then into seconds

$3 \times 60 = 180 \: minutes$

$180 \times 60 = 10800 \: seconds$

• Then we have to add all the seconds

$300 + 10800 + 7$

$= 11107$ seconds
