Answer 2

Answer:

5 m/s

Step-by-step explanation:

Given : A vehicle moving with a speed of 18 km/h

To Find : A vehicle cover in 1 second

Solution:

Speed of vehicle = $18 km/hr$

1 km = 1000 m

1 hour = 3600 seconds

Speed of vehicle = $18 \times \frac{1000}{3600}  m/s$

Speed of vehicle = $18 \times \frac{10}{36}  m/s$

Speed of vehicle = $18 \times \frac{5}{18}  m/s$

Speed of vehicle = $5 m/s$

Hence The speed in m/second is 5 m/s .
