Question

Rahul a cyclist rides 40 km to the east turn north and rides 20 km again turns left and rides 20 km how far is he form the standing point

Answer 1

cyclist rides 40km to the east .
see figure, Line AB = 40km

then, cyclist turns north and rides 20km
see figure, line BC = 20km

again he turns left and rides 20km.
see figure , line CD = 20km

we have to find how far , is he from starting point.

so, cyclist distance from the starting point = AB - CD
= 40km - 20km = 20km

Answer 2

The cyclist at first rides 40km to the east .

Let A be the starting point, thus Line AB = 40km

Next, the cyclist turns north and rides 20km

Let line BC = 20km

He then turns left and rides 20km.

Let line CD = 20km

Therefore, distance of the cyclist from the starting point = AB - CD

= 40km - 20km = 20km

The cyclist is located at a distance of 20km east of the starting point.
