Problems Based on Speed
Solving Statements Involving Speed
Solving Statements Involving Speed: In these types of problems we consider the relative speed of the two objects. When the two objects are moving in the same direction, the relative speed is the difference of the speed of the two objects. When the two objects are moving in the opposite direction , the relative speed is found as the sum of speed of the two objects.
For Example: The distance between two points A and B is 340 Km. Two trains start together one from station A and other from station B , The speed of one train is 5 km/hr more than the other train. If the distance between the two trains after two hours is 30 km. Find the speed of the two trains.
Let the speed of one train = x km/hr
Speed of other train will be = x +5 km/hr
Distance = Speed X time
Distance travelled by first train in two hours = 2x
Distance travelled by the second train in two hours = (x+5) X 2= 2x+10
Distance between the two trains after two hours = 30km
According to the question
Distance travelled by one train + distance travelled by second train + 30 = 340
2x+ 2x+ 10 + 30 = 340
4x+ 40 = 340
4x= 300
x= 75 km/hr
Speed of one train = 75 kmhr
Speed of second train = 75 + 5 = 80 kmhr
In a flight of 2800 km, an aircraft was slowed down due to bad weather. Its average speed for the trip was reduced by 100 km/hr and the time increased by 30 minutes. Find the original duration of the flight. | |||
