Distance between Mumbai and Pune is (2y2+y+2). There are two routes to travel from Mumbai to Pune as shown in the figure.
What is the difference between the distance covered through the two routes?
When y=5
Distance=(2y2+y+2)
=2×52+5+2=50+5+2
=57units
When y=3,
Distance=(2y2+y+2)
=2×32+3+2=18+3+2
=23units
∴ Required difference = 57 – 23 = 34 units.
