The solution to problem 26 from the Grade 4 Mathematics textbook (Moro & Bantova, Part 1) involves adding the distances covered by two cyclists moving toward each other [1]. By converting 1 km 180 m to 1,180 m and adding the second cyclist's distance of 820 m, the total distance closed is 2,000 meters, or 2 km [1]. Detailed solutions can be found on Skysmart.
