Answer:
(A)d=20h
Step-by-step explanation:
If Kia rides her bike at 20 miles per hour.
20 miles per hour is referred to as the Kia's Speed.
Now we know that:
Given:
- Number of hours traveled=h
- Distance traveled=d
- Speed = 20 mph
Substituting these three into the formula above, we have:
Cross multiply
d=20h
<u>The correct option is A.</u>
Answer: First, you need to figure out 22 times 2 = 44. Then, you need to multiply the original ratio by 44 to get the answer.
