Q:
A) 1.5 hrs | B) 1.7 hrs |
C) 2.2 hrs | D) 3.5 hrs |
Answer: C) 2.2 hrs
Explanation:
Explanation:
Let the original Speed be "s" kmph
And the usual time be "t" hrs
Given that if the bus is running at 9s/10 kmph the time is 22 hrs
=> [9s/10] x 22 = t x s
=> 99/5 = t
=> t = 19.8 hrs
Hence, if bus runs at its own speed, the time saved = 22 - 19.8 = 2.2 hrs.
