Question

Rahul studied science for $\frac{1}{3}$ hour and English for $\frac{1}{3}$ hour? How long did he study?

Answer 1

We have,

Rahul studied science for $=\frac{1}{3}hour=\frac{1}{3}\times 60=20min.$

English for $=\frac{1}{3}hour=\frac{1}{3}\times 60=20min.$

Total time$=20+20=40min.$

Or $\frac{40}{60}hr=\frac{2}{3}hr.$

Hence, this is the answer.
