Answer 5

You can calculate this in miles per minute or miles per hour.
To calculate miles per minute you divide the miles by the minutes. To calculate the miles per hour you need to calculate how many fractions of an hour you have and multiply by the inverse. So 15 is 1/4 of an hour so you multipl the miles by 4 to get the miles per hour. 30 minutes is 1/2 an hour so you multiply by 2.
So for miles per hour the answers are:
\[10*4=40\frac{miles}{hour}\]
\[23*2=46\frac{miles}{hour}\]
For minutes we end up with decimals or fractions:
\[\frac{10}{15}=\frac{2}{3}\frac{miles}{minute}\]
\[\frac{23}{30}\frac{miles}{minute}\]
