Show Answer

Answer:

Correct Answer: E

Solution:

  • Distance between two cities $ =350km $ Distance travelled by Sunil with the speed of 80 km/h in $ 2\frac{1}{4}h $ or $ 2.25h=80\times 2.25km=180km $ Remaining distance $ =35-180=170km $ Speed $ =60km/h $ Time taken to reach in city $ X=\frac{170}{60}=2.83h $ Total time $ 2.25+2.83=5.08h $

$ \therefore $ $ \approx 305\min =5h5\min $ Sunil started journey at 5: 55 am and finished the journey = 11: 00 am
