Explanation:
After
Therefore, we can see that she has traveled:
They want the answer in miles per hour, so we need to convert 10 minutes to 1 hour (60 minutes):
Therefore, we must also multiple the miles traveled by 6:
After converting, you can now see that she has traveled
3 miles per hour
Explanation:
So speed (velocity) is:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
But we need the count of miles for 1 hour. So we need to change the 10 minutes into 1 hour
But 60 minutes is the same as 1 hour. so by substitution in the denominator we have:
So the speed (velocity) is 3 miles per hour
