Question

Karan can walk a distance of 2.1 m in 30 minutes. Find the time taken by him to cover a
distance of 5.6 km.
​

Answer 1

Speed of Karan = Distance/Time

= 2.1m / 30 min

= 2.1m / 0.5 hr

= 4.2 m/hr

Time = Distance / Speed

= 5.6 km / (4.2 m/hr)

= 5600 m / (4.2 m/hr)

= (56000 / 42) hr

= 1,333.3 hours = 55.5 days

NOTE: In case if Karan walked 2.1 km in 30 min (which is more realistic) then the answer is about 1.3 hours.
