Question

A car travels 30 1/5 miles in 2/3 of an hour.What is the average speed in miles per hour of the car

Answer 1

The speed of car is 45.3 miles per hour.

Further explanation:

Speed is the rate at which an object changes position with respect to time.

Given

$Distance = 30\frac{1}{5}\ miles\\Time=\frac{2}{3}$

The formula for calculating speed is:

$Speed = \frac{distance}{time}\\= \frac{30\frac{1}{5}}{\frac{2}{3}} \\=\frac{\frac{151}{5}}{\frac{2}{3}} \\=\frac{151}{5}*\frac{3}{2}\\=\frac{453}{10}\\=45.3\ miles\ per\ hour$

The speed of car is 45.3 miles per hour.

Answer 2

The average speed in miles per hour of the car is 45.3.

The distance traveled by the car is  $30\dfrac{1}{5}\;\rm{miles}$

Time taken by the car to cover the distance is  $\dfrac{2}{3}\;\rm{hours}$

We need to calculate the average speed in miles per hour of the car.

Therefore,

The formulated way to represent the speed of the car is given as:

$\rm{Speed}=\dfrac{Distance}{Time\;taken}$

Thus, substitute the given values and solve them further.

$\begin{aligned}\rm{Speed}&=\dfrac{30\dfrac{1}{5}}{\dfrac{2}{3}}\\&=\dfrac{\dfrac{150+1}{5}}{\dfrac{2}{3}}\\&=\dfrac{{151 \times 3}}{2 \times 5}\\&=45.3\;\rm{miles \;per \;hour} \end{aligned}$

Hence, the average speed in miles per hour of the car is 45.3.
