Ram took 15 minutes 30 seconds to reach his friend's house which is 900 meters away. The speed of Ram (in km/h) is (correct to two decimal places)
Answer & explanation
Correct answer: option 1
15 minutes 30 seconds = 15 × 60 + 30 = 930 seconds
We know,
Speed = \(\frac{900}{930}\) m/sec
To convert m/sec into km/h
X m/sec × \(\frac{18}{5}\) = y km/h
= \(\frac{900}{930}\) × \(\frac{18}{5}\)
= 3.48 km/h
