Question

3.2 A bus is travelling at a s
peed of 50 km/hr. How much distance will it cover in
3 mins?
​

Answer 1

Answer:

2500 miter

Step-by-step explanation:

if 1 hour=50km,then

60 mins=50km,then

3 mins=?

          =3*50/60

          =2.5km

if 1 km=1000 m, then

2.5km=?

         =2.5*1000

         =2500m

       

Answer 2

Given:-

Speed of Bus - 50 kmph ⇒ 50 ×  $\frac{5}{18}$  =  $\frac{250}{18} = \frac{125}{9}$ m/s

Time - 3 mins - 60 × 3 = 180 sec

To Find:-

Distance travelled

Explanation:-

Using Formula   $speed = \frac{distance}{time}$

⇒ $\frac{125}{9}$ = $\frac{distance}{180}$

⇒ Distance = $\frac{125}{9}$ × 180

⇒ Distance = 125 × 20

⇒ Distance = 2500

∴ Distance it will cover in 3 mins is 2500 m or 2.5 kms

----------------------------------------------------------------------------------------------

Note:- The S.I Unit of Speed = m/s ( meters / seconds )

----------------------------------------------------------------------------------------------

So we converted the kmph into m/s and minutes into seconds
