Correct Answer: 3 km and 4 km


Solution : According to the instructions given, the diagram is as follows –

Now, we have to find the values of X and Y.

Here, A is the starting point and C is the finishing point.
AB = X km; BC = Y km; AC = 5 km
By applying the Pythagorean theorem –
(AC) 2 = (AB) 2 + (BC) 2
⇒ (5) 2 = (X) 2 + (Y) 2
⇒ 25 = (X) 2 + (Y) 2
⇒ 25 = (3) 2 + (4) 2
And, 25 = 9 + 16

So, the value of X and Y is 3 km and 4 km. Hence, the first option is correct.
