Zoya started doing yoga at 19:17 and did this for 109 minutes. At what time did she stop?

Given :

Zoya started doing yoga at 19:17.

She did yoga for 109 minutes.

To do :

We have to find the time she stops.

Solution :

We know that,

$1 hour = 60 min$

Therefore,

109 min $=$ 60 min $+$ 49 min $=$ 1 hour 49 min.

This implies,

She stopped yoga at 19 hour 17 min $+$ 1 hour 49 min $=$ 20 hour $+$ 66 min $=$ 20 hour $+$ 60 min $+$ 6 min $=$ 20 hour $+$ 1 hour $+$ 6 min $=$ 21 hour 6 min.

Therefore, Zoya stopped yoga at 20:06.
