Question

A ELECTRIC TRAIN IS MOVING WITH A VELOCITY OF 126KM/H.HOW MUCH DISTANCE HE WILL COVER IN 40 MINUTES?

Answer 1

here ,
v=126 km /h
=126 x 1000 m/60min
= 126000m/60min
= 12600m/6 min
=2100m/ min
Now,
distance covered in 1 min is 2100m
therefore distance covered in 40 mins
=40 x 2100 m
=84000m
hope it's the required answer...
