Thief Police

Given :-

• Speed of Thief = 23 km/h
• Speed of police = 27 km/h
• Distance between them = 12 m = 0.012

To find :-

• Time taken to catch the thief by the police

Solution :-

Here ,

Speed of police is 27 - 23 = 4 km/h is greater than the thief

Finding time using

Speed = Distance/time

Simplifying

Time = distance/speed

→ Time = 0.012/4

→ Time = 0.003 hrs

Hence , time taken by the police to catch the thief = 0.003 hours.

Answer 2

Step-by-step explanation:

Given that, a thief was running at a speed of 23 km / hr and a policeman chasing him was running at a speed of 27 km / hr . If the distance between them is 12 m.

We have to find the time taken by the police to caught the thief.

Speed between police and thief = 27 - 23 = 4 km/hr = 4 × 5/18 = 10/9 m/s

Distance is 12 m.

Now,

Time = Distance/Speed

Assume that the time taken is x sec.

Substitute the values in the above formula,

→ x = 12/(10/9)

→ x = 12*9/10

→ x = 10.8

Hence, the time taken is 10.8 sec or 0.003 hr.
