Question

The initial odometer reading of a cab is 369 km. It travelled for 2 hours and the final odometer reading showed 469 km. Find the approximate average speed of the cab.:
a) 14 m/s
b) 11 m/s
c ) 8 m/s
d) 17 m/s​

Answer 1

Answer:

17 m/s  

Explanation:

time=2 hr

distance=496-369

             =127 km

speed=distance/time

v=S/t

 =127/2

  =63.5 kmph

km/h⇒m/s-->multiply with 5/18

63.5 kmph⇒m/s  =  63.5×5/18

                             = 17.63 m/s

                              =17 m/s                 [approx.]
