a=1/4pid^2
4a=pid^2
4a/pi=d^2
square both sides to get d
Answer: Square root of 4a over pi equals d.
The answer to your question is d<0
In this question, we're comparing the two car trips that were give to us.
We know that the Jones family drove 200 miles in 5 hours
We also know that the Grant family drove 360 miles in 6 hours.
Lets see how many miles each family drives in 1 hour
Jones Family:
200 ÷ 5 = 40 mph
Grant Family:
360 ÷ 6 = 60 mph
We see that the Grant family travels more per hour than the Jones family.
This means that our comparison between the two car trips is that the Grant Family is going faster.
