Three runners running around a circular track can complete one revolution in 2,4 and 5.5 hours when will they meet at the starting point?(answers is coming 44 hours, I am not getting same answer,please help).
Answers
Answer:
Step-by-step explanation:
2, 4, 5.5
CONVERT HOURS INTO MINUTES
2 = 120 MINS, 4= 240 MINS, 5.5 = 330 MINS
TAKE LCM FOR 120, 240, 330
SO.. THE LCM IS 2640
MEETING TIME = 2640/60
= 44
44 IS THE ANSWER
THEY WILL MEET AFTER 44 HOURS
Given,
Three persons took time to finish one round = 2, 4, 5.5hrs.
To Find,
The time they took to meet each other at the starting point.
Solution,
Given that,
There are three runners.
And they took 2, 4, 5.5hr respectively to complete one round.
Let's convert it into minutes.
2hr = 120mnts.
4hr = 240mnts.
5.5hr = 330mnts.
Then need to find the LCM of these
LCM(120, 240, 330)
2640 mnt.
Therefore, convert it into hr
2640 / 60 =44hr.
Hence, 44hr is the time three runners took to meet at the starting point.
