Answer:
a 1800
b1800 and c 1800 time
Answer:
540 times all the lights blinks together in 1 hour.
Step-by-step explanation:
Given:-
A red light blinks 3 times in one minute.
A yellow light blinks 6 times in two minutes.
A green light blinks 3 times in one minute.
To find:-
The number of times all the three lights blink together in 1 hour.
1 hour = 60 minutes
According to the question,
The number of times a red light blinks in 1 minute = 3
So, the number of times a red light blinks in 60 minutes = 3 × 60
= 180 times
The number of times a yellow light blinks in 2 minute = 6
The number of times a yellow light blinks in 1 minute = 6/2
= 3 times
So, the number of times a yellow light blinks in 60 minutes = 3 × 60
= 180 times
The number of times a green light blinks in 1 minute = 3
So, the number of times a green light blinks in 60 minutes = 3 × 60
= 180 times
Thus, the number of times all the light blinks in 60 minutes (1 hour) is,
= 180 + 180 + 180
= 540 times
Therefore, 540 times all the lights blinks together in 1 hour.
