shaunti drove 621miles in 11.5 hours.wht was her average speed in miles per hour?
I presume that all you have to do is divide the amount of miles that she drove by how long she drove.
621miles/11.5hours=54miles/hour
I did this for a quiz and got 54!
54 mph
To calculate the average speed, you need to divide the total distance traveled by the total time taken. In this case, Shaunti drove 621 miles in 11.5 hours.
Average speed (in miles per hour) = Total distance / Total time
Therefore, to find Shaunti's average speed, you can use the formula:
Average speed (in miles per hour) = 621 miles / 11.5 hours
Now, let's calculate it:
Average speed = 621 / 11.5
Average speed ≈ 53.91 miles per hour
So, Shaunti's average speed was approximately 53.91 miles per hour.
