Question

Rahul a cyclist rides 40 km to the east turns north and rides 20 km again turns left and rides 20 km. How far is he from the starting

Answer 1

Answer:

28.28 km

Step-by-step explanation:

40 km to East

then 20 km to North

Then turn left means go West side for 20km  means (-20 km East)

So Rahul is 20 km North  from starting point

& 40 - 20 = 20 km East from starting point

Distance = Sqrt ( 20^2 + 20^2 )  = 20 * sqrt (2) km

= 20 * 1.414 = 28.28 km
