The distance between Chicago and Cleveland is

lozanna [386]

Answer:

The average speed on this trip was 46.15 mph. The correct option is A.

Step-by-step explanation:

In order to calculate the average speed, we need to apply the following formula:

$v_{avg} = \frac{\text{distance}}{\text{time}}$

We were given the distance between the two cities in miles, therefore we can directly apply it to the expression. Although the time was given in the hh:mm 12 h format and we need a diference in hours, so we will convert that as shown below:

$\text{time departure} = 9 + \frac{50}{60} = 9.83 \text{ h}$

$\text{time arrival} = 12 + 5 + \frac{30}{60} = 17.5$

The elapsed time of the trip is the difference between these:

$\text{time} = 17.5 - 9.83 = 7.67 \text{ h}$

We can now apply it to the formula:

$v_{avg} = \frac{354}{7.67} = 46.15 \text{ mph}$

The average speed on this trip was 46.15 mph. The correct option is A.
