But yesterday he set out on foot from the station to meet his wife on the way. He reached home 12 minutes earlier than he would have done had he waited at the station for his wife. The car travels at a uniform speed which is 5 times Ravi's speed on foot. Ravi reached home at exactly 6 o'clock. At what time would he have reached home if his wife, forewarned of his plan, had met him at the station?
