The Copeland family started out on a family vacation with plans to visit several states. First, Mr. Copeland drove 163 miles in 3 hours and 49 minutes. Then, Mrs. Copeland took over, driving 411 miles in 6 hours and 27 minutes. What is the family's average speed so far?

Add up all the times
avg speed = total distance / total time
Well, it seems like the Copeland family is really on the move! Let's calculate their average speed so far, shall we?
First, let's convert Mr. Copeland's time to hours. 3 hours and 49 minutes is approximately 3.82 hours (since there are 60 minutes in an hour).
Next, let's calculate Mrs. Copeland's time to hours as well. 6 hours and 27 minutes is approximately 6.45 hours (since there are 60 minutes in an hour).
Now, let's calculate the total distance traveled by both Mr. and Mrs. Copeland. Mr. Copeland drove 163 miles, while Mrs. Copeland drove 411 miles. So, the total distance is 163 + 411 = 574 miles.
To find the average speed, we need to divide the total distance by the total time. The total time is 3.82 hours + 6.45 hours = 10.27 hours.
Therefore, the family's average speed so far is 574 miles ÷ 10.27 hours ≈ 55.9 miles per hour.
So, the Copeland family's average speed so far is approximately 55.9 miles per hour. Looks like they're cruising along pretty nicely on their vacation!
To find the family's average speed, we need to calculate the total distance traveled and the total time spent.
First, let's convert the time into minutes for easier calculation.
Mr. Copeland's time: 3 hours + 49 minutes = 3 * 60 minutes + 49 minutes = 180 + 49 = 229 minutes.
Mrs. Copeland's time: 6 hours + 27 minutes = 6 * 60 minutes + 27 minutes = 360 + 27 = 387 minutes.
Now, let's calculate the total distance traveled:
Total distance = Mr. Copeland's distance + Mrs. Copeland's distance
= 163 miles + 411 miles
= 574 miles.
And the total time spent:
Total time = Mr. Copeland's time + Mrs. Copeland's time
= 229 minutes + 387 minutes
= 616 minutes.
Finally, to find the average speed, we divide the total distance by the total time:
Average speed = Total distance / Total time
= 574 miles / 616 minutes
= 0.932 mph (rounded to three decimal places).
Therefore, the family's average speed so far is approximately 0.932 mph.
To find the family's average speed, we need to calculate the total distance traveled by the family and the total time taken.
First, let's calculate the total distance traveled. Mr. Copeland drove 163 miles, and Mrs. Copeland drove 411 miles. So the total distance traveled by the family is 163 + 411 = 574 miles.
Next, let's calculate the total time taken. Mr. Copeland drove for 3 hours and 49 minutes, which is equivalent to 3.8167 hours (since there are 60 minutes in an hour, so 49 minutes is 49/60 = 0.8167 hours). Mrs. Copeland drove for 6 hours and 27 minutes, which is equivalent to 6.45 hours (27/60 = 0.45). So the total time taken by the family is 3.8167 + 6.45 = 10.2667 hours.
Now, we can calculate the average speed by dividing the total distance traveled by the total time taken: average speed = total distance / total time = 574 miles / 10.2667 hours ≈ 55.95 miles per hour.
Therefore, the family's average speed so far is approximately 55.95 miles per hour.
