Julia can finish a 20 mile bike ride in 1.2 hours. katie can finish the same bike ride in 1.6 hours. how much faster does julia ride than katie?

Julia rode 4.17 miles per hour faster than Katie.

Step-by-step explanation:

Julia can finish a 20 mile bike ride in 1.2 hours.

Katie can finish the same bike ride in 1.6 hours.

Julia finished the bike ride faster than Katie, so we have to calculate how much Julia is faster.

Now we have to calculate the difference of the speed of both.

Speed =  

Julia's speed = = 16.67 miles/hour

Katie's speed = = 12.5 miles/hour

The difference between the speed = 16.67 - 12.5 = 4.17 miles/hour

Therefore, Julia rode 4.17 miles per hour faster than Katie.
