Answer:
It will take 4.71 hours to travel a distance of 221.43 miles
Step-by-step explanation:
Given
Distance covered in time 7.99 hours is  375.32 miles.
Now we know that speed is equal to distance per unit time.
Therefore, 

Which is the constant speed, hence now time taken for a distance of 221.43 miles will be

Therefore, the time taken to cover 221.43 miles is 4.71 hours.

Answer:
B
Step-by-step explanation:
From the given information:
Sienna has $8 denotes the unit blocks of x tiles. So, she saved $3 per week.
This implies that:
8x + 3(1) = 8x + 3
Also,
If Jacob as well had $6 which implies 6x unit block of tiles while he saved $4; 
i.e.
6(x) + 4(1) = 6x + 4
So;
the model that can determine when Sienna will have the same amount as Jacob is:
8x + 3 = 6x + 4
