A transport truck covers a route track of 480 km in 8 hours. How much time will it require to clear a distance path of 360 km given it tracks at the same speed?
A. 5.5 hours
B. 6.0 hours
C. 7.0 hours
D. 6.5 hours
Answer: Option B
Solution (By JKSSB Mock Tests)
Speed of truck = 480 / 8 = 60 km/h. Time taken for 360 km path = 360 / 60 = 6 hours.
A vehicle covers a specific highway distance at 50 km/h. If it spikes its speed to 60 km/h, it clears the stretch 20 minutes early. Find the total distance.
Explanation:
Time difference = 20 minutes = 20/60 = 1/3 hours. Let distance be d. d / 50 - d / 60 = 1/3 => (6d - 5d) / 300 = 1/3 => d / 300 = 1/3 => d = 100 km.
Two trains 100 meters and 120 meters long are running in the same direction at speeds of 72 km/h and 54 km/h respectively. In how much time will the faster train cross the slower train completely?
