If a man riding his bicycle covers 150 meters in 25 seconds then what is his speed in km / hour?

If a man riding his bicycle covers 150 meters in 25 seconds then what is his speed in km / hour? Correct Answer 21.6

Given:

Distance covered = 150 meters

Time = 25 seconds

Formula used:

Speed = Distance/Time

Calculation:

Speed = 150/25 m/s

⇒ 6 m/s = 6 × (18/5) km/hr

⇒ 108/5 km/hr 

⇒ 21.6 km/hr

∴ The speed in km/hr is 21.6 km/hr

Each of the question below consists of a question and three statements number I, II and III given below it. You have to decide whether the data provided in the statement are sufficient to answer the question. If the bus is travelling from Surat to Ahmadabad and a car is travelling from Ahmadabad to Surat, then what is the distance between Surat and Ahmadabad? I. The speed of a car is 40% less than the speed of bus. Bus started at 9 am and car started at 10 am and they meet at 3 pm of the same day. II. After travelling for 1 hour, because of traffic average speed of bus is decreased by 20% and covers distance between Surat to Ahmadabad in 11 hours. Original speed of car is 20% less than original speed of bus and before crossing bus it covered 200 km if starts 1 hour later than bus. After crossing car, bus covers remaining distance in 5 hours. III. Speed of bus is 10 km/hr more than the speed of car and before crossing car ratio of distances covered bus and car in same time was 5 : 4. Time taken by car to cover the distance between Ahmadabad and Surat is 2 hours 15 minutes more than time taken by bus to cover the same distance.
What is the distance covered by boat N upstream in 5 hours? Which of the following option is sufficient alone to find the answer? A) Boat M is travelling downstream with 20% more downstream speed of boat N. Speed of boat M in still water is 10% more than the speed of boat N in still water. B) Boat M and Boat N are travelling downstream with speed 33 km/hr and 40 km/hr respectively and speed of boat M is still water is 2 times the speed of stream. C) Speed of boat M in still water is 6 km/hr less then speed of boat N in still water and speed of stream is 10 km/hr. D) Speed of stream is ½ times the speed of boat N in still water and downstream speed of boat M is 44 km/hr. E) Speed of stream is 10 km/hr and ratio of upstream speed of boat M and boat N is 3 : 2 respectively.
The speed of a car during the 2nd hour of its journey is thrice of that in the 1st hour. Also, its 3rd-hour speed is the average speed in the first two hours. If the car had traveled for the entire duration at the speed of 2nd-hour speed then it would have traveled 150 km more. By what percent distance covered in the first case will decrease than distance covered in the latter case in the same time i.e. 3 hours?
