Question

find the distance covered by an object in 2 minutes at the speed of 13.5 m/sec

Answer 1

Time = 2 minutes
         = 2*60
         = 120 seconds
Speed = 13.5 m/s
  13.5   = Distance/ 120
Distance= 13.5 *120
              = 135 * 12
              = 1620 meters
              = 1.62 km

Therefore, distance covered = 1620 meters or 1.62 km

Answer 2

Distance covered per second=13.5 m
so, distance covered per minute =13.5×60=810
Hence distance covered in 2 minute=810×2=1620 m or 1.62 km
