Which is Less Time - Same Units (Level 2)

This math topic practices the concept of calculating time taken given speed and distance, all while expressing these values in consistent units. Students are asked to compare scenarios to determine which option results in a shorter time, reinforcing their understanding of the relationship between speed, distance, and time. Various scenarios are presented, including different creatures and objects moving at specific rates and distances. The problems are aimed at enhancing problem-solving skills in a real-world context by applying mathematical concepts.
