Question from Anil, a student: 3 cars are moving at speed of 4 kmph,5.5 kmph and 8 kmph in a circular track.The circular track has How to solve this..? please help me..? |
Hi Anil.
To go one full lap (11 km), car A takes 11/4 hours, car B take 11/5.5 hours and car C takes 11/8 hours.
Therefore the question is really asking for the lowest common integer multiple of these three fractions!
Write back if you need more hints.
