Question

A football team loses $4$ yards every $15$ minutes. How many yards did the team lose after an hour?

• A. $60$ yards
• B. $16$ yards
• C. $90$ yards
• D. $30$ yards

Answer 1

The correct option is B $16$ yards

We know $60$ minutes = $1$ hour.

As per the given situation, the football team loses $4$ yards every $15$ minutes.
$\therefore$ Number of yards the football team loses in $1$ minutes $=\frac{4}{15}$ yards

Number of yards the football team loses in $60$ minutes $=60\times$ Number of yards football team loses in $1$ minute
$\Rightarrow$ Number of yards football team loses in $60$ minutes $=$
$(60\times \frac{4}{15})$ yards

$=\frac{60\times 4}{15}$ yards

$=\frac{240}{15}$ yards $(\because 60\times 4=240)$

Now, $240÷15$ can be evaluated as:



$\therefore 240÷15=16\text{R}0$

Hence, the football team would lose $16$ yards after an hour, i.e., option (b.) is the correct answer.
