The rainmode family drove 1764 miles across the united states under vacation. it's took a total of 28 hours, right is solve a multiplication equation to find the average speed in miles per hour.

Average speed= 63 miles per hour.

Step-by-step explanation:

Given:

Distance covered by rain-mode Family =1764 miles

Number of hours taken for the journey =28 hrs

To find the average speed,let it be 'S'.

We know that,

Distance is the multiplication of speed and time.

Distance covered = Average speed * Total time taken.

Dividing both sides with time.

Average speed (S) = Distance covered/ Total time taken

Note: Average speed (S) =Total distance covered divided by total time taken.

So,

Average speed = miles per hour.

So the final answer is 63 miles per hour.
