Will it take more time or less time to travel a greater distance? Of course it will take longer, so we have direct proportionality and we need the fraction that makes the time longer. We need to multiply 10 minutes by 6.8/1.3. This fraction looks simpler if we get rid of the decimals by multiplying top and bottom by 10, i.e.,68/13. Multiply this by 10 minutes and we get 680/13. That comes to 52 and 4/13 minutes. 4/13 of a minute is 4/13*60=240/13=18 seconds approximately. So the answer is 52 minutes 18 seconds.
