ANSWER: 
Time taken to reach the destination of the trip is 2 hours 
SOLUTION: 
Given, a day trip was planned which is 110 miles away on any of the path available. 
So, we can consider that, distance to be travelled is 110 miles 
And if the average speed of the traveler is 55 miles per hour, then what is the time taken to reach destination. 
We know that distance is given as 

Where, d is distance travelled 
s is the average speed 
t is the time taken to reach destination 
By substituting the values we get, 

 = 2
 = 2
Hence the time taken to reach the destination on trip is 2 hours
