Answer:
Car A blinks 36 more times than Car B
Step-by-step explanation:
To figure out how many times Car A blinks, you have to divide 60 / 5 which equals 12. Since it blinks 7 times per 5 seconds, you would have to multiply 7 by 12, which equals the answer for the first part, 84 times per minute.
To figure out many times Car B blinks, it's the same way. But this time, you multiply 12 by 4, since it blinks 5 times every 4 seconds. Which in that case is 48 times per minute.
So, 84 - 48 = 36 times more than Car B
