Video Summary

The problem involves a kangaroo that jumps uphill and downhill, with each downhill jump covering three times the distance of an uphill jump. It takes 2,024 jumps in total. By setting variables for uphill (u) and downhill (d) jumps, and knowing each uphill jump is 1 meter while each downhill is 3 meters, we determine that u = 3d because uphill jumps are three times as frequent as downhill jumps. Solving 4d = 2,024 gives d = 506, thus u = 1,518. The total distance is 1,518 meters uphill plus 1,518 meters downhill, totaling 3,036 meters.
