Show Answer

Answer:

Correct Answer: E

Solution:

  • Distance [d] = 30 km Speed (v) $ =36km/h $
    $ \Rightarrow $ Then, $ v=\frac{d}{t} $ $ Time,(t),=\frac{d}{v}=\frac{30}{36} $
    $ \Rightarrow $ $ t=\frac{5}{6}h $ If speed = 42 km /h Then, distance cover by the scooter in the same time $ =\frac{5}{6}\times 42=5\times 7=35,km $
