Light travels extremely rapidly (c = 3.00×108 m/s ). Suppose you had to travel 40 miles to work every day. If you traveled at the speed of light for the entire trip, how long would it take you to get to work (in seconds)? [1 mile = 1.61 km]

Respuesta :

Given , Speed of light = 3 × 10⁸ m/s 
             Distance = 40 × 1.61× 1000 m 
                           = 264400 m
 We know that, speed = distance/time 
                   so, time = distance/speed
                             t = 264400 / 3 × 10⁸
                             t = 0.00881333 sec  Approx
The answer is 0.00881333 sec  Approx
