A sound wave takes 4 seconds to travel a distance between two structures. If the speed of sound is 340 m/s, what is the distance between the structures in kilometers?
A. 1.50 km
B. 1.24 km
C. 1.36 km
D. 1.42 km
Answer: Option C
Solution (By JKSSB Mock Tests)
Distance = Speed * Time = 340 * 4 = 1360 meters. Converting to kilometers = 1360 / 1000 = 1.36 km.
A motorboat registers a speed of 15 km/h in still water. It takes 4 hours to cover a certain distance upstream. If the stream velocity is 3 km/h, find the distance covered.
