Answer 1

Answer: (B), (D)

The correct options are
B

1.25 hrs

D

125.5 hrs

$\text{We know that 1 km = 1000 metres.}\therefore 4km=4000\text{metres}.\text{The time taken to travel 4km is same as the time taken to travel 4000 metres.}\text{Therefore the time required to cover 4000 metres is also 2.25 hours=135 mins}.$
