Open in App

Solution

Since, $2$ hrs $40$ mins $= (2 \times 60) + 40$ mins $= 120 + 40 = 160$ mins as $1$ hour = $60$ minutes.
So, given ratio can be written as $48$ min $: 2$ hours $40$ min
$= 48 : 160$
$= 4 \times 12 : 4 \times 40$
$= 12 : 40$
$= 4 \times 3 : 4 \times 10$
$= 3 : 10$
$∴$ the simplest form is $3 : 10$
