speed = Distance / time
time = 20 mins
distance covered = 15 km
15 km / 20 mins = 3/4 km / mins
speed in km / hr .
now we will convert mins into hrs
1 hr.=60 mins
20 mins = 20/60= 1/3 hr .
nkw we will apply the speed formula
15/1/3 = 45 km / hr
time = 20 mins
distance covered = 15 km
15 km / 20 mins = 3/4 km / mins
speed in km / hr .
now we will convert mins into hrs
1 hr.=60 mins
20 mins = 20/60= 1/3 hr .
nkw we will apply the speed formula
15/1/3 = 45 km / hr
