To find the longest time you can stop, first we need to calculate the maximum distance you can travel in 9.6 hours. 
Distance= Speed x Time 
Maximum distance= 65 mi/h x 9.6 h= 624 miles

Now subtract the distance traveled from the maximum distance to find the distance you can cover while stopping for dinner:

Distance while stopping= 624 miles - 541 miles= 83 miles

To find the maximum time you can stop, divide the distance while stopping by the maximum speed:

Time= Distance/ Speed 
Time= 83 mi/ 65 mi/h= 1.3 hours

Therefore, the correct answer is B) 1.3 h.
