Azlyn can ride her horse 15.2 miles per hour. She is in an endurance race that is 76 miles
Tema [17]

Step-by-step explanation:

Remember, math is a language

when you see per think fractions

15.2 miles per hour = 15.2 miles / 1 hour

since this is a fraction, Units can cancel just like numbers

To cancel miles and be left with hours rearrange the fraction

1 hour / 15.2 miles

then multiply by 72 miles

\frac{1hour}{15.2miles}  \times 72miles

the miles cancel and youre left with hours!

so youd write and solve 72 / 15.2
