50 km in one hour then
distance covered in 1/1/2 hour = 50+1/2×50
=75 km is the distance covered by ramit daily
if he is 15 minute late then
his speed should be
1/15×75=5
50+5=55
his speed should be 55 km/ h
distance covered in 1/1/2 hour = 50+1/2×50
=75 km is the distance covered by ramit daily
if he is 15 minute late then
his speed should be
1/15×75=5
50+5=55
his speed should be 55 km/ h
