Thus, the time taken to cover 9 miles is 
<u>Speed:</u>
The speed can be determined using the formula,

Substituting the values, we have;

Simplifying, we get;



Thus, Jasmine's speed is 10.8 miles per hour.

Answer:
y = 218
Step-by-step explanation:
Mean = (Sum of all numbers)/(How many numbers present)
27 = (20 + 2y + 25 + y + 30)/27
27 = (3y + 75)/27
3y + 75 = 729
3y = 729 - 75
3y = 654
y = 218
