Show Answer

Answer:

Correct Answer: A

Solution:

  • Time and speed are inversely proportional.

$ \therefore $ $ =\frac{7}{6}\times $ Usual time $ - $ Usual time = 25 min

$ \Rightarrow $ Usual time $ ( \frac{7}{6}-1 )=25\min $

$ \Rightarrow $ Usual time $ \times \frac{1}{6}=25\min $

$ \therefore $ Usual time $ =25\times 6=150\min =2,h,30\min $
