Q:
A) 8 hrs | B) 7.5 hrs |
C) 7 hrs | D) 6.5 hrs |
Answer: A) 8 hrs
Explanation:
Explanation:
Given speed of the bike after servicing = 55 kmph
Time taken for travelling some distance at 55 kmph = 5 hrs
Then,
Distance = Speed x Time = 55 x 5 = 275 kms.
Now,
Speed of the bike before servicing = 35 kmph
Distance = 275 kms
Now, Time = Distance/Speed = 275/35 = 7.85 hrs =~ 8 hrs.
