Question

A car took 2 hours to travel 198 km, then speed in m/s is

Answer 1

Answer:

Given, Distance s = 198 km

= 198 x 1000 m

= 198000 m

time t = 2 h

= 2 x 60 x 60 sec = 7200 sec

speed or velocity v = to find

We know that,

s = v x t

$v\: =\:\frac{s}{t}\\\\=\:\frac{198000}{7200}\\\\=\:27.5 ms^{-1}$
