Question

. John took 42 min to bicycle to his grandmother's house, a total of 4 km. What

was his speed in km hr -1

?​

Answer 1

distance took by John in 42 min is 4000 meters

distance covered by John per min=4000/42

distance covered in 60 min=4000/42x60=5714.286m/s

Now convert m/s to Km/hr = m/s X 5/8

= 5714.286X5/I8=I587.3I437
