Hey there! :)
Answer:
First part: 2 miles.
Second part: 45 minutes
Third part: 8 mph.
Step-by-step explanation:
We can divide this question into 3 parts.
Begin by solving for the distance traveled after 15 minutes by creating a ratio:
Cross multiply:
20 · 15 = 150 · x
300 = 150x
300/150 = 150x/150
x = 2 miles.
2nd part: How long it took her to ride 6 miles.
Set up another ratio similar to the one used before:
Cross multiply:
20 · x = 6 · 150
20x = 900
20x/20 = 900/20
x = 45 minutes.
3rd part:
For this part, we will need to convert from minutes to hours.
Therefore, her speed is 8 mph.
Keep 6/15 the same and change Division sign into a multiplication sign and flip 4/21 and that will become 21/4. 
126/60=21/10 and 21/10 as a mixed number is 2 1/10 so your answer is 2 1/10. Hoped I helped. :)
