If a train is running 4 minutes late and losing 4 seconds per minute. how many more minutes will it take for the train to running half an hour late?

5 answers

They want minutes so do it all in minutes

4 seconds = 4/60 = 1/15 minute

half hour = 30 minutes

30 = 4 + (1/15) t

26 * 15 = t

t = 390 minutes

(which is 6.5 hours)
