Question

A police man saw a Thief from 200m. Thief ran away and the policeman started following him. speed of a thief is 10 km/h and of police is 11 km/h. Then what will be the distance between police and thief after 6 minutes?

Answer 1

see
the difference between the theif and police is 200m if the police ran with the speed 11km/h then he will travel 1.1km in 6min and the theif Will cover 1km distance in 6 min as the theif was initially the theif was far 200m from police therefore the distance between police and theif will be
1200-1100
i.e 100m
therefore the distance between police and theif after 6 min would be 100m

Answer 2

The distance between the thief and police= 200m
The speed of the police= 11km/h
the speed of the police in 1 hour or 60 minutes= 11/60
then the distance covered by the police in 6 minutes= 11/60*6
= 1.1 km
and in the same way, the thief will cover 1km in 6 minute
therefore the distance between the police and thief= 1200-1100
= 100m
