Two trains arrived at a station at 2: 55 p. m., with one arriving on track a, and the other arriving on track b. trains arrive on track a every 16 minutes, and they arrive on track b every 18 minutes. at what time will trains next arrive at the same time on both tracks?

a) 4: 07 p. m.
b) 5: 19 p. m.
c) 6: 31 p. m.
d) 7: 43 p. m.

B) 5:19 P.M.

Step-by-step explanation:

Given that two trains arrived at a station at 2:55 P.M., with one arriving on Track A, and the other arriving on Track B. Trains arrive on Track A every 16 minutes, and they arrive on Track B every 18 minutes.

Now we need to find about at what time will trains next arrive at the same time on both tracks.

Then next time trains arrive at the same time on both tracks. can be found by taking least common multiple of 16 and 18 minutes.

Multiples of 16 and 18 are

163248648096112128144160

1836547290108126144162180

Least common multiple of both is 144

Hence both trains will arrive at the same time after 144 minutes

or at (2:55 PM+144 minutes)

= (2 hours 55 min)+(144 min) PM

= (2 hours 55 min)+(2 hours 24 min) PM

= (2 hours 55 min)+(2 hours 24 min) PM

= 5 hours 19 minutes

Hence correct choice is B) 5:19 P.M.

i think it is 18
