Calculate May’s average speed as she travels from her home in Singapore to her uncle and aunt’s house in the Philippines. Use the steps below. First, use May’s travel summary to find the total distance May travelled. Include every part of her trip: walk, bus ride, flight and taxi ride. Next, calculate the total time May spent travelling. Finally, use the formula to find her average speed. Convert all times to hours; round all distances to the nearest kilometre.
Total distance: ___
Time walking: 15 minutes = 0.25 hours
Time on bus: 45 minutes = 0.75 hours
Flight time: 3.5 hours
Time in taxi: 1 hour
Irfan enjoys horse riding. Early one morning, he rode a horse through the woods. The horse trots for 18 minutes and covers a distance of 4 km. It then speeds up to a canter and covers 7 km in 10 minutes. Irfan takes a 20-minute break to rest and enjoy the scenery. Finally, he sets off again and the horse gallops back home, covering 6 km in 6 minutes.

Look at the picture of person A on the left and person B on the right pushing a crate. Underline the correct word: When the crate is not moving, the magnitude of the force each person applies is equal / different.
Look at the picture of person A on the left and person B on the right pushing a crate. Underline the correct value: If the forces are balanced, the resultant (net) force acting on the crate is 10 N / 0 N.
Look at the picture of person A on the left and person B on the right pushing a crate. Person A pushes with a force of 50 N and person B pushes with a force of 40 N. What happens to the crate?
Look at the picture of person A on the left and person B on the right pushing a crate. Person A pushes with a force of 50 N and person B pushes with a force of 40 N. Draw arrows representing the forces on the picture. Label the magnitudes of the forces.
