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".

so since this is true
x is the same as the corresponding angle which is 47 degrees
x = 47 degrees
