Answer :
To find the average speed when traveling 172 miles in 4 hours, we can use the formula for speed:
$$
\text{Speed} = \frac{\text{Distance}}{\text{Time}}
$$
Here, the distance is 172 miles and the time is 4 hours. Plugging the values into the formula gives:
$$
\text{Speed} = \frac{172 \text{ miles}}{4 \text{ hours}}
$$
Performing the division:
$$
\text{Speed} = 43 \text{ miles per hour}
$$
So, the distance is 172 miles, the time is 4 hours, and the calculated average speed is 43 miles per hour.
$$
\text{Speed} = \frac{\text{Distance}}{\text{Time}}
$$
