Ashwin and Donald decided to set out from two towns on their bikes, which are 247 miles apart, connected by a 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? explanatory solutions

Let the number of miles Donald has been cycling be x.
The number of days of the adventure is 3x.
Ashwin has been cycling 9 miles a day, so Ashwin has covered 3x * 9 miles = 27x.
The total distance is 247 miles
Add the distance that Ashwin and Donald have been cycling for
x+27x = 147
Once you solve for x, you can calculate how the distance each person has cycled respectively
Let the number of miles Donald has been cycling be x.
The number of days of the adventure is x + 3
Ashwin has been cycling 9 miles a day

Equation
Total # of days x ( # of miles of Ashwin per day + # of miles of Donald per Day) = 247
(x + 3)(9 + x) = 247 ----- Find the positive roots

the root is 10
so, x = 10
The number of days of the adventure is x + 3
so, x + 3 = 10 + 3 = 13 days
ashwin = 9 miles x 13 days = 117 miles
Donald = 10 miles x 13 days = 130 miles
