A student waiting at a stoplight notices that her turn signal, which has a period of 0.80 s, makes one blink exactly in sync with the turn signal of the car in front of her. The blinker of the car ahead then starts to get ahead, but 15 s later the two are exactly in sync again. Part A What is the period of the blinker of the other car

he period  of the blinker of the other car = 0.747 s

Explanation:

The period of the blinker of the 1st car = 0.80 seconds

The other came is 1/15 times slower than the first car =  1/15 * (0.80) = 0.053

The period of the the blinker of the other car = Period of the blinker of the first car - ( Difference in the periods of the blinkers of the two cars)

The period of the blinker of the other car = 0.80 - 0.053

The period  of the blinker of the other car = 0.747 s
