Their speed of separation will be equal to the sum of their speeds because they are in opposite directions.
Speed of separation = 40 + 50 = 90 miles per hour
Time = distance / speed
Time = 405 / 90
Time = 4.5 hours

if you're solving for the surface area of a rectangular prism then it's 304 :D
7/16 is your answer to this problem
Answer:
1/8
Step-by-step explanation:
The probability of picking a 3 is 1/4.
The probability of picking an even number is 2/4.
1/4 × 2/4
2/16 = 1/8
You would think it should be B. That's the second best answer. The actual question says that you want the square root of 1764
sqrt(2^2 * 3^2 * 7^2) = 2 * 3 *7
sqrt(1764) = 42
