A man travel 3 miles,turn left and travels 6 miles,then left again and travels 8 miles.how far is he from the starting point?
Answers
Given : A man travels 3 miles, turns left and travels 6 miles, then left again and travels 8 miles.
To Find : How far is he from the starting point?
Solution:
Turning left two time is equivalent to U turn (reverse direction)
A man travels 3 miles
turns left and travels 6 miles
then left again and travels 8 miles => ( 8 miles are in opposite direction to 3 miles )
Hence 6 miles in one direction and ( 3 - 8) = - 5 miles in other direction and both are perpendicular
Hence Distance from starting point = √(-5)² + 6²
= √25 + 36
= √61
= 7.8 miles
