Correct Answer - Option 3 : 375 meters
Given:
A man and a woman start moving towards each other with a speed of 9 km/h and 4.5 km/h respectively.
Formula used:
Distance = Speed × Time
Speed adds up if the moving direction is opposite.
Calculation:
First convert km/h into m/s
To convert km/h into m/s multiply by 5/18
⇒ 9 × (5/18) = 2.5 m/s
⇒ 4.5 × (5/18) = 1.25 m/s
⇒ Speed = 2.5 + 1.25 = 3.75 m/s
Time is 1 minute and 40 seconds means 100 seconds
⇒ Distance = 3.75 × 100 = 375 meters.
∴ The difference between the man and woman is 375 meters before 1 minute 40 seconds they meet.
