The time interval in which your friend beats you is determined as 4.2 minutes.
<h3>Time in which you catch up with your friend</h3>
The time interval in which your friend beats you is determined from the principle of relative velocity.
(Va - Vb)t + (Vc - Vd) = d
(6 - 3)t - (6 - 9)t = 1500
6t = 1500
t = 1500/6
t = 250 s
Time in minutes = 250 s/ (60s/min) = 4.2 minutes
Thus, the time interval in which your friend beats you is determined as 4.2 minutes.

Answer:
Both particle and wave properties
Explanation:
Light is defined as a particle and a wave, and even as a combination of a particle and a wave. A unit of light is the photon. Higher energy photons behave like particles and low energy photons behave like waves.
Experiments performed with light indicate that light exhibits both particle and wave properties.
