Question

Rohit goes 350 km in 5 hours. Find:
(i) his speed
(ii) the distance covered by Rohit in 6.2 hours
(iii) the time taken by him to cover 210 km.

Answer 1

Distance covered = 350 km

Time taken = 5 hours

(i) ∴ Speed = ${\displaystyle \frac{\text{Distance}}{\text{Time}}}$

= ${\displaystyle \frac{350}{5}}$

= 70 km/h

(ii) Distance covered in 6.2 hours

= 70 × 6.2 km

= 434 km

(iii) Time taken to cover 210 km

= ${\displaystyle \frac{\text{Distance}}{\text{Time}}}$

= ${\displaystyle \frac{210}{70}}$ hr

= 3 hours
