A cyclist covers a distance of 170 meters in 17 seconds. The time taken by the cyclist to cover the distance of 6 km, shall be how much?
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → 10 minutes
At a steady speed, time = distance ÷ speed. The speed is found from the given run first, in metres per second, and the 6 km is changed to metres to match.
Speed \(\displaystyle =\frac{170}{17}=10\) m/s
Distance \(=6\) km \(=6000\) m
Time \(\displaystyle =\frac{6000}{10}=600\) s \(=\) 10 minutes
