Initial velocity of John's car (V1) = 0 miles per hour
Final velocity of John's car (V2) = 45 miles per hour
Time taken for acceleration = 45 seconds
Then
Acceleration = (V2 - V1)/Time taken
= (45 - 0)/15 miles per hour per second
= 45/15 miles per hour per second
= 3 miles per hour per second.
So the approximate rate of change in the miles per hour that John's car accelerated is 3 miles per hour per second. The correct option among all the options given in the question is option "A".
Answer:
i told you in the comment it equals 7
Step-by-step explanation:
Yea i agree LOL and meatballs are very very yuum e
Use substitution
y = 2(-y + 6)
y = -2y + 12
3y = 12, y = 4
4 = 2x, x = 2
Solution: x = 2, y = 4
