A map has a scale of \(1:2\,500\,000\). The distance between Singapore and Phuket is 1314 km. Calculate the distance, in centimetres, between Singapore and Phuket on the map.[2]
When a ball is dropped, the distance, \(d\) metres, it falls is directly proportional to the square of the time, \(t\) seconds, from when the ball is released. The distance from which the ball is dropped is increased by 44%. Calculate the percentage change in the time taken for the ball to reach the ground.[2]
