To solve the problem step by step, we can follow these steps: ### Step 1: Understand the Problem The cyclist travels a total distance of 60 km. He covers the first 20 km at a speed of 20 km/h. We need to find out the speed at which he must travel the remaining 40 km to achieve an average speed of 10 km/h for the entire trip. ### Step 2: Calculate the Total Time for the Trip To find the required speed for the remaining distance, we first need to calculate the total time allowed for the entire trip if the average speed is to be 10 km/h. ...
