Distance and Speed to Time - Changed Time Units (Level 3)

This topic involves advanced problems related to calculating time from distance and speed, with a twist of converting the time into different units. It requires understanding the relationships between speed, distance, and time, along with conversion between units such as seconds, minutes, hours, days, millimeters, meters, centimeters, and kilometers. Problems are framed in real-life contexts involving vehicles, animals, and other moving objects, pushing learners to apply formulae flexibly. Each problem offers multiple choice answers, emphasizing both problem-solving and unit conversion skills.
