Walking at 7/9 of his usual speed, a man reaches his destination 16 minutes late. Find his usual time.
A. 64 minutes
B. 56 minutes
C. 60 minutes
D. 50 minutes
Answer: Option B
Solution (By JKSSB Mock Tests)
New speed = 7/9 of usual speed => New time = 9/7 of usual time. Difference = 2/7 of usual time = 16 minutes. 1/7 of usual time = 8 minutes => Usual time = 56 minutes.
Excluding minor platform corridor stops, the speed of an express route train is 84 km/h, and including stops it tracks at 70 km/h. How many minutes does it spend resting at stops per hour?
Excluding stoppages, a transit truck travels at 75 km/h and including stoppages it travels at 62.5 km/h. How many minutes does the truck stop per hour?
