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:

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:


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

We can now apply it to the formula:

The average speed on this trip was 46.15 mph. The correct option is A.
There are 12 inches in a foot so we can work this problem out in inches 3/5 is 80%......80% of 12 inches is 9.6 inches ....1/4 is 3 inches and 2/3 is 8 inches so we have 9.6,3,and8 now we multiply 9.6*3*8 for the answer to be 230.4 inches squared
First you add like terms, so in this case it would be 2x+3x, which would together make 5x=10. Then to get x isolated divide 10 by 5 and x=2
