Question

The speed of a cycle is 12 km/h. how many minutes will it take to cover a distance of 800 metres?​

Answer 1

Speed of cycle = 12km/hr == 12 × 5 / 18 = 10/3 m/s

Distance = 800 meters

Time taken == 800 × 3 / 10 == 240 seconds = 4 minutes

Or

Distance covered in 1hr = 12 km

1km == 1/12 hr == 1000 meter =5 min

800 meters == 5/1000 × 800 = 4minutes
