The stopping distance d meters of a car is inversely proportional to the square of its speed s km/h when the brakes are applied. A car travelling at 50 km/h requires a stopping distance of 20 metres.
If the stopping distance is 500 metres, what is the speed of the car when the brakes
are applied?

Arestaurant gives out a scratch-off card to every customer. the probability that a customer will win a prize from a scratch-off card is 25%. design and conduct a simulation using random numbers to find the experimental probability that a customer will need more than 3 cards in order to win a prize. justify the model for your simulation, and conduct at least 10 trials.
