If a person travels \(10\displaystyle\frac{1}{5}\) km in 3 h, then the distance covered by him in 5 h will be:
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → 17 km
At a steady speed, the distance is proportional to the time, so the speed is found first and then used for 5 hours.
Distance covered in 3 h, as an improper fraction: \(\displaystyle10\frac{1}{5}=\frac{51}{5}\) km
Speed, the distance covered in one hour: \(\displaystyle\frac{51}{5\times3}=\frac{17}{5}\) km/h
Distance in 5 h, five times that: \(\displaystyle\frac{17}{5}\times5=17\) km
