At his usual rowing rate, Rahul can travel 12 miles
downstream in a certain river in 6 hours less than it takes
him to travel the same distance upstream. But if he could
double his usual rowing rate for his 24 - mile round trip, the
downstream 12 miles would then take only one hour less
than the upstream 12 miles. What is the speed of the
current in miles per hour?​
