1.Consider three Airports A, B, and C. Two friends Ananya and Madhuri want to meet at Airport C. Ananya Boarded Flight 1 from Point A to C which is 1200 km, due to bad weather, Flight 1 slowed down, and the average speed was reduced by 200 km/h and the time increased by 30 minutes. Madhuri boarded Flight 2 from Point B to C which is 1800 km, the average speed of Flight 2 is 720 km/h. What is the waiting time, and who will be waiting at the airport? (Given Ananya and Madhuri boarded at the same time)


In question 1 What is the speed of flight 1 in km/hr if weather good (Actual Speed of flight 1).

Answer question no. 5 and 6 based on the information mentioned below.

A water fountain is designed to shoot a stream of water in the shape of a parabolic arc. The equation of the parabola is given by ℎ(�)=−0.5�2+4�+1, where ℎ(�) represents the height of the water stream in meters and t  represents the time in seconds since the water was shot. Answer the following questions.
