Question

Ronaldo played piano on his bithday party. He played piano cover for five different songs. If each piano cover takes two minutes thirty seconds to play. How long will it take him to play five in a row?

• A. $12$ minutes
• B. $12\text{minutes}\&10\text{seconds}$
• C. $12\text{minutes}\&30\text{seconds}$

Answer 1

The correct option is C $12\text{minutes}\&30\text{seconds}$

Time spent in playing the piano cover for one son $=2$ minute $30$ seconds

$\therefore$ Time spent in playing piano cover of 5 different songs is the multiplication of $2$ minute $30$ seconds by $5$,


It is $10$ minutes $150$ seconds.
$\because 1\text{minute}=60\text{seconds}$
$\Rightarrow 150\text{sec}=150÷60=2\text{min}\&30\text{sec}$

$\Rightarrow 10\text{min}+150\text{sec}=10\text{min}+2\text{min}+30\text{sec}=12\text{min}+30\text{sec}$

$\therefore$ Time spent in playing piano cover of 5 different songs $=12\text{min}\&30\text{sec}$

Therefore, (c) is the correct option.
