Question

A movie starts at $10\text{A.M.}$ and ends at $11:45\text{A.M.}$ Movie takes hours to complete.

• A. $\frac{3}{4}$ hrs
• B. $\frac{1}{4}$ hrs
• C. $1\frac{3}{4}$ hrs

Answer 1

The correct option is C $1\frac{3}{4}$ hrs

As movie starts at $10\text{A.M.}$ and ends at $11:45\text{A.M.}$ that means the movie completes in $1$ hour and $45$ minutes.

Converting $45$ minutes to hours:
$\because 60\text{minutes}=1\text{hour}\Rightarrow 1\text{minute}=\frac{1}{60}\text{hour}\therefore 45\text{minutes}=\frac{45}{60}\text{hour}=\frac{15\times 3}{15\times 4}=\frac{3}{4}\text{hour}$

Therefore, movie completes in $1\frac{3}{4}\text{hours}$
