Question

a boy covers a distance of 1.2km in 40min , find his speed in km per hours​

Answer 1

Given :-

• A boy covers a distance of 1.2km in 40min , find his speed in km per hours​

Solution :-

• First of all, to find his speed in kmph (kilo metre per hour) , let us convert the time into hours

       40 min =  $\sf\frac{40}{60}$ = $\sf\frac{2}{3}$ hours

• Now, we know that,

       Speed = $\sf\frac{distance }{time}$

    ⇒ Speed = $\sf\frac{1.2}{\frac{2}{3} }$ = $\sf\frac{1.2 \times 3}{2}$ = 1.8 kmph

∴ Speed of the boy is 1.8 kmph (kilo metre per hour)
