A man walks at 6 m/sec and reaches his destination in 20 minutes. A woman covers the same distance in 1.2 hours. What is the speed of the woman (in km/h)?
Answer & explanation
Correct answer: option 1
Distance = Speed × Time
20 minutes = 1200 sec
Distance = 6 × 1200 = 7200 m
= 7.2 km
Speed of woman = \(\frac{Distance}{Time}\)
= \(\frac{7.2}{1.2}\)
= 6 hours
