A helium balloon leaves the ground at a point A and rises vertically at uniform speed. At the end of 5 minutes, Raju finds the angular elevation of the balloon as 30°. If the point at which Raju is standing is 550 m away from point A, what is the speed of the balloon in m/s?
The tickets numbered from 1 to 30 are mixed up and then a ticket is drawn at random. What is the probability that the ticket has a number which is a multiple of 3 or 5?
Length of the train is equal to the distance covered by train to cross the pole. So, we will find the distance traveled by the train in 7 seconds by applying the following formula:
Distance= Speed x Time
Speed is given in Km/hr so we will convert it into m/s as answers are given in meters.
