This math topic focuses on calculating the duration of specific events given constant speeds and varying distances. It practices using formulae related to speed, distance, and time, requiring students to manipulate these variables and perform unit conversions. The problems feature diverse scenarios involving different speeds (e.g., meters per millisecond, millimeters per hour) and distances, challenging the learners to convert and calculate time correctly. This set of problems is part of an advanced module on speed, distance, and time.
