Question

A bus is travelling at a speed of 50 km/hr. How much distance will
it cover in 3 mins?
(a) 5.2 km (6) 2 km (c) 2.5 km
(d) 5 km​

Answer 1

Answer:

c) 2.5

Step-by-step explanation:

speed= distance/time

(NB: change hour into min)

Answer 2

Answer:

option c ) 2.5 km

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

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
