Question

the turn signal on a car A blinks 3 times every 5 seconds. The turn signal on car B blinks 2 times every 3 seconds . In one minute, how many more times will the turn signal blink on car B than the turn signal on car A

Answer 1

In one minute, car A's turn signal blinks 36 times, and car B's turn signal blinks 40 times. Therefore, car B's turn signal blinks 4 more times than car A's.

Step-by-step explanation:

The question involves calculating the difference in the number of times two car turn signals blink in one minute. First, let's calculate how many times each turn signal blinks in one minute.

For car A, the turn signal blinks 3 times every 5 seconds. There are 60 seconds in a minute, so in one minute, car A's turn signal will blink:

(60 seconds / 5 seconds) × 3 blinks = 12 × 3 blinks = 36 blinks.

For car B, the turn signal blinks 2 times every 3 seconds. In one minute:

(60 seconds / 3 seconds) × 2 blinks = 20 × 2 blinks = 40 blinks.

Now, to find how many more times car B's signal blinks compared to car A:

40 blinks (car B) - 36 blinks (car A) = 4 more blinks for car B.

Therefore, in one minute, the turn signal on car B will blink 4 more times than the turn signal on car A.

Answer 2

B=2t/3 and A=3t/5

B-A=(2t/3)-(3t/5)

B-A=(10t-9t)/15

B-A=t/15 and the time we are concerned with is when t=60 so

B-A=60/15=4

So B will blink 4 more times than A in one minute.
