Answer 1

Answer:

90 hrs

Step-by-step explanation:

let 20 min=3hrs

then 600min(10hrs)= 20*30 min

20*30=3*30

600=90hrs

Answer 2

Answer:

Sweta takes 90 hours to finish his project

Step-by-step explanation:

Sweta projects require 10 hours of work

Thus, project requires (\,10 \times 60=600\hspace{0.1cm}minutes)\,(10×60=600minutes) of work

Now, Sweta works on his project 20 minutes every 3 hours

Let us consider 3 hours as 1 interval

Thus, work completed in 1 interval =20\hspace{0.1cm}mins=20mins of work

Number of intervals =\frac{600}{20}= 30\hspace{0.1cm}intervals=20600=30intervals

Total Hours required =30 \times 3=90\hspace{0.1cm}hours=30×3=90hours

Hence, Sweta takes 90 hours to finish his project
