The distance between two stations is 240 km. A train takes 4 hours to cover this distance. Calculate the speed of the train

find the distance between two points A(4, 3) and B(8, 6)

What is the distance between two base pairs in DNA?

Represent the following situations in the form of quadratic equations : A train travels a distance of 480 km at a uniform speed. If the speed had been 8 km/h less, then it would have taken 3 hours more to cover the same distance. We need to find the speed of the train.

A new unit of length is chosen such that the speed of light in vacuum is unity. What is the distance between the Sun and the Earth in terms of the new unit if light takes 8 min and 20 s to cover this distance ?

The odometer of a car reads 57321.0 km when the clock shows the time 08:30 AM. What is the distance moved by the car, if at 08:50 AM, the odometer reading has changed to 57336.0 km? Calculate the speed of the car in km/min during this time. Express the speed in km/h also

From a station two trains start at the same time. One train moves west and the other moves north. First train moves 5 km/hr faster than the second train. If, after 2 hours, the distance between the two trains is 50 km, find the average speed of each train.

A train travels 360 km at a uniform speed. If the speed had been 5 km /h more, it would have taken 1 hour less for the same journey. Find the speed of the train.

A motor boat takes 6 hours to cover 100 km downstream and 30 km upstream. If the boat goes 75 km downstream and returns back to the starting point in 8 hours, find the speed of the boat in still water and the speed of the stream.

An express train takes 1 hour less than a passenger train to travel 132 km between Mysore and Bangalore (without taking into consideration the time they stop at intermediate stations ). If the average speed of the express train is 11km/h more than that of the passenger train , find the average speed of the two trains.

A train covered a certain distance at a uniform speed. If the train would have been 10 km/h faster, it would have taken 2 hours less than the scheduled time. And, if the train were slower by 10 km/h , it would have taken 3 hours more than the scheduled time. Find the distance covered by the train.
