11. Ashwin and Donnld decided to set out from two towns on their bikes, which are 247 miles apart, connected by
straight Roman road in England. When they finally met up somewhere between the two towns, Ashwin had been
cycling for 9 miles a day. The number of days for the whole adventure is 3 more than the number of miles that Donald
had been cycling in a day. How many miles did each cycle?​
