Question

how long will a 2m long auto rickshaw travelling at a speed of 30 km per hour take to cross 1 M white zebra crossing

Answer 1

It's speed in m/s =30*18/5=108m/s
Time taken to cover 108m=1s
Time taken to cover 1m=1/108s

Answer 2

Answer:

0.36 s

Step-by-step explanation:

Distance to cover    = 2 m + 1 m = 3m

Speed of the auto rickshaw  = 30km/h

Convert to m/s   = 30 x 5/18                          

                           = 8.333

Time taken to pass the zebra crossing  t = d/s

     = 3/8.33

     = 0.36 s
