Answer:

We must think that the cars are traveling 630 miles in six hours.

Their combined speeds are x and x+25.

distance = velocity * time

Since, velocity = distance / time

(x + x + 25) = 630 / 6

2x + 25 = 105

2x = 80

So x = 40 mph  and the other car's velocity is 65 mph.

Answer:

6 feet

Step-by-step explanation:

Since there are 8 bricks and each brick is 9 inches long, that is a total of 72 inches. Now, you need to convert it from inches to feet. Since 1 foot is 12 inches, we need to divide 72 by 12 to get the number of feet. 72 / 12 is equal to 6.
