Geeta taught in the classroom for 2 hours and 25 minutes in the morning and 1 hour and 45 minutes in the afternoon. How long was she teaching in all?

$\huge{\bf{\green{\mathfrak{\dag{\underline{\underline{Answer:-}}}}}}}$

She taught in morning = 2 hr 25 min

She taught in afternoon = 1 hr 45 min

She teaches in all = She taught in morning + She taught in afternoon

= 2 hr 25 min + 1 hr 45 min

= 3 hr 70 min

We know that, 60 min = 1 hr

∴ 3 hr 60 min = 3 hr 60 min + 10 min = 4 hr 10 min
