Answer 2

Given :-

• shabna takes 20 minutes to reach the school if she goes at the speed of km/h if she wants to reach school at 24 min

To find :-

• what should be her speed in km/h

Solution :-

$\sf⟼time(1) = 20min$

$\sf⟼speed = \frac{6km}{hr} \times \frac{5}{18} = \frac{5m}{3s}$

$\sf⟼speed = \frac{distance}{time}$

$\sf⟼distance = speed \times time$

$\sf⟼distance = \frac{5m}{3s} \times 20 = \frac{100m}{3}$

$\sf⟼time(2) = 24min$

$\sf⟼speed = \frac{distance}{time}$

$\sf⟼speed = \frac{100m}{3} \times \frac{1}{24}$

$\sf⟼speed = \frac{25m}{18s} \times \frac{18}{5}$

$\sf⟼speed = 5kmhr$

so therefore the speed of her is 5km/hr
