Question

, 5: Peter walks 5 m towards West, takes a right turn and walks 5m again. He then takes another right turn How far and walks 20m. He then takes a Ònal right turn and walks 5m before stopping. How far is he from the starting point?

Answer 1

In the figure, P is the starting point of Perter.

Q is the point of his first right turn which is 5m from the starting point.

R is the next point of his right turn which is again 5m from P.

T is another right turn which is 20m from R.

U is the stop point which is 5m from T.

It is clear that P is the starting point and U is the stop point.

We need to find PU.

From figure, PU = ST but ST = RT - RS and RS = QP

Therefore, PU = RT - QP

PU = 20 - 5 = 15m.

Hence, he is 15m far from the starting point.
