# Find the average velocity of a car which travels 360 km in 6 hours, show in m/s and km/h ?

Jul 4, 2018

Divide the distance by the time you will get average velocity (or more properly: average speed).

#### Explanation:

$\text{360 km"/"6 h" = "60 km/h}$

This is equal to $\text{16.7 m/s}$ because

$\text{60 km" = "60 km" xx "1000 meters"/"1 km" = "60000 meters}$

$\text{1 hour" = "60 min" xx "60 seconds"/"1 min"= "3600 s}$

So

$\text{60 km/h" = "60000 m"/"3600 s" = "16.7 m/s}$

Average velocity $v = 60$ $\frac{k m}{h} , = \frac{50}{3} \frac{m}{s}$

#### Explanation:

Average velocity (v) = distance travelled (d) / time taken (t).

Given : Distance travelled = 360 km, time taken = 6 hours.

$v = \frac{d}{t} = \frac{360}{6} = 60$ $\frac{k m}{h}$

$1 k m = 1000 m , 1 h o u r = 60 \cdot 60 = 3600 \sec$

$\therefore v = \frac{60 \cdot 1000}{3600} = 60 \cdot \frac{5}{18} = \frac{50}{3}$ $\frac{m}{\sec}$
