Speed Distance Time Worksheet

Quantitative aptitude lesson 18: Speed, distance and time · Set 390 · 40 questions

The method (D = S × T): Distance = speed × time; time = distance ÷ speed. Change minutes to hours by ÷ 60. km/h → m/s: × 5/18. m/s → km/h: × 18/5. Average speed = total distance ÷ total time. Same distance there and back at a and b: average speed = 2 × a × b ÷ (a + b).
