Shelby drove to her aunt's house, which is 360 miles away. If it took her 5 hours and she drove at a constant rate, what was Shelby's average speed?
My answer which I figured out in two different ways:
360 miles/5 hours=72 mph
360 miles/5 hours=x/1 hour=72 mph
Can you please double check my answer to see if I am correct?
Thank you
both ways are fine.
You're correct!!!(: ;)!!!!

Yes, your answer is correct. You have correctly calculated the average speed of Shelby's drive to her aunt's house to be 72 miles per hour.
To double-check your answer, let's review how you arrived at it:
Method 1:
You divided the total distance (360 miles) by the total time (5 hours), which gives you the average speed in miles per hour.
360 miles / 5 hours = 72 miles per hour
Method 2:
You set up a proportion to find the average speed for 1 hour. You know that in 5 hours, Shelby covered 360 miles, so you can set up the following proportion:
360 miles / 5 hours = x miles / 1 hour
By cross-multiplying and solving for x, you find that x = 72 miles per hour.
Both methods yield the same result, confirming that Shelby's average speed was indeed 72 miles per hour. Well done!
