Question

How many seconds are there in $2$ days?

Answer 1

Compare hours, minutes, and seconds:

The units in which time is measured are seconds, minutes, and hours.

We know,

$1$ minute $=60$ seconds

$1$ hour $=60$ minutes

$1$ day $=24$ hours

Now, it can be calculated that,

$1$ hour $=60\times 60$ seconds

$\Rightarrow$ $1$ hour $=3600$ seconds

So, $1$ day $=3600\times 24$ seconds

$\Rightarrow$ $1$ day $=86400$ seconds

$\Rightarrow$ $2$ days $=2\times 86400$ seconds

$\Rightarrow$ $2$ days $=172800$ seconds

Hence, in 2 days, there are $172800$ seconds.
