A man is walking at a speed of 12 km/h. After every km, he takes rest for 3 minutes. How much time will he take to cover a distance 6 km?
Answer & explanation
Correct answer: option 4
Time = \(\frac{Distance }{Speed}\)
= \(\frac{6 }{12}\)
= 0.5 hour
= 30 minutes
After every km man takes rest for 3 minutes . SO , During 6 km he stops for 5 times .
Total rest time = 3 × 5 = 15 minutes
Total time taken = 30 + 15 = 45 minutes
