Question

A girl travels along a straight line, from point A to B at a constant speed, $V_1$ meters/sec for T seconds. Next, she travels from point B to C along a straight line, at a constant speed of $V_2$ meters/sec for another T seconds. BC makes an angle 105° with AB. If CA makes an angle 30° with BC, how much time will she take to travel back from point C to A at a constant speed of $V_2$ meters/sec, if she travels along a straight line from C to A?

• A. 0.5(√3 – 1)T
• B. T
• C. 0.5(√3 + 1)T
• D. √3T
• E. None of the above

Answer 1

Answer: (C)

0.5(√3 + 1)T

Answer 2

The correct option is (C) : 0.5(√3 + 1)T
