A pupil left home for school at a speed of 5 km/h and returned at a speed of 4 km/h. The whole journey took 5 h 24 min. How far is the school from home, in kilometres?
Rono cycled from town R at an average speed of 72 km/h and took 3 hours 30 minutes to reach town S. Kepha cycled the same distance and took 4 hours. At what average speed was Kepha cycling?
My happiness is when i see pupils struggle to learn and am here to make their work easier, efficient and free.
