Question

A school bus covers a distance of 6 km in 0.5 h. Calculate its
speed in km/h and m/s. (Speed= 12 km/h; 3.3 m/s)​

Answer 1

Answer:

Step-by-step explanation:

Given,

Distance(d) = 6km

Time(t) = 0.5h

To Find :-

Speed of the bus(s)

Formula Required :-

$Speed=\dfrac{distance}{time}$

s = d/t

Solution :-

$Speed=\dfrac{6km}{0.5h}$

$=\dfrac{6}{\dfrac{5}{10}}km/hr$

$=\dfrac{6\times 10}{5}k /hr$

$=6\times 2km/hr$

= 12 km/hr

We know that :-

$1km/hr=\dfrac{5}{18}m/s$

$\implies 12km/hr=12\times \dfrac{5}{18}m/s$

$=\dfrac{60}{18}m/s$

= 3.33 m/s

Speed = 12 km/hr = 3.33 m/s
