To find the cyclist's speed for the entire trip, we need to calculate the total distance traveled and the total time taken.

 

Calculate total distance:

Distance traveled in the first part: 11 km

Distance traveled in the second part: 25 km

Total Distance = 11km + 25km = 36km

 

Calculate total time:

Time taken for the first part: 35 minutes

Time taken for the second part: 55 minutes

Total Time=35minutes+55minutes=90minutes

 

Convert total time to hours:

 

Then, calculate average speed:
