Question

Mr. Christopher went on a road trip in his car. In $1^{\text{st}}$ hour, he travels $53$ miles. In $2^{\text{nd}}$ hour, he travels $50$ miles, and in $3^{\text{rd}}$ hour, he travels $47$ miles before reaching to a gas station. On an average, the distance travelled by him in an hour is miles.

Answer 1

Representing the distance covered by Mr. Christopher in each hour in the table below.
Distance Travelled on an Hourly Basis

Time	Distance Covered (in miles)
$1^{\text{st}}$ hour	$53$
$2^{\text{nd}}$ hour	$50$
$3^{\text{rd}}$ hour	$47$

The average distance covered by Mr. Christopher in an hour
$=\frac{\text{Total distance covered (in miles)}}{\text{Total duration (in hours)}}$
$=\frac{53+50+47}{3}\text{miles/hour}$
$=\frac{150}{3}\text{miles/hour}$
$=50\text{miles/hour}$

$\therefore$ On an average, the distance travelled by Mr. Christopher in an hour is $50\text{miles}$.
