Question

a car travels a distance of 200 km in 3 hours find the speed of the car in m/s​

Answer 1

Answer:

$distanc \: = 200km = 200000m$

$time = 3hour = 10800second$

$speed = \frac{distance}{time}$

$speed = \frac{200000}{10800} = \frac{2000}{108}$

$speed = 18.51852.... \frac{m}{s}$

I hope it is help for you..........

Answer 2

Answer:

18.51 m/sec

Explanation:

distance = 200 x 1000m

time = 3 × 60 x 60 secs

speed = distance ÷ time

= 200000 ÷ 3 x 3600

= 2000 ÷ 108

= 18.51 m/sec
