Kevin and Daniel were rowing their canoe along the River Trent.

In the morning they managed to row upstream at an average speed of 2 miles per hour.

They then stopped for a spot of lunch and a nice rest.

In the afternoon, the pace was a little easier as they were now rowing downstream, and managed an average speed of 4 miles an hour.

The morning trip took them 3 hours longer than the afternoon.

How far did they row upstream?
