Question

a man covers 15 km in 5 hours.Find his speed in a- m/min and b- m/ sec with solution​

Answer 1

First of all we convert 5 hours into minutes for that multiply 5*60= 300
And 1km=1000m so 15km Will be 15000 m
Now speed= distance/time 15000/300= 50m/min
Now sec than again multiply 300 with 60 for converting into sec
300*60=18000 now divide distance with this value
15000/18000=0.8333
