Here is your answer to your question

Mark my answer as brainliest and thank me

Step-by-step explanation:

Ritu time spent = 3hrs and 20 min =200min

She spent for science work sheet =3/5

So left over time is 2/5

$\frac{2}{5} \times 200 = 40min$

There she spent 160 min means 2 hrs 40 min for science work sheet and left over time is 40 min.
