Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e 1:30 pm
The thief starts at 10:30 am at 50 km/hr
Owner starts chasing at 11:00 am (after 30 mins) at 60 km/hr
In 30 minutes, thief covers 25 km
Owner gains on thief at 10 km/hr (60 - 50)
Time to catch = 25 ÷ 10 = 2.5 hours
2.5 hours after 11:00 am = 1:30 pm
