Question

How many seconds are there in $\frac{2}{3}$ of $2hours?$

Answer 1

We know that

$$\begin{gathered} 1minute=60seconds \\ 1hour=60minutes \\ \therefore 1hour=60\times 60seconds \\ 1hour=3600seconds \\ 2hours=2\times 3600seconds \\ 2hours=7200seconds \end{gathered}$$

According to the question, seconds are there in$\frac{2}{3}$of $2hours$

It means that $\frac{2}{3}$ of $7200seconds$$=$$\frac{2}{3}\times 7200$

$$\begin{gathered} =\frac{2\times 7200}{3} \\ =\frac{14400}{3} \\ =4800 \end{gathered}$$

Therefore, seconds are there in$\frac{2}{3}$of $2hours$$=$$4800seconds$
