b) Which bus has a greater speed? (1)

Answer 1

Answer :-

a)Bus A covered greater distance than bus B.

b)Bus A has greater speed than bus B.

Explanation :-

Given :

Distance covered by bus A => 35 metre

Time taken by bus A => 5 seconds

Distance covered by bus B => 39 metre

Time taken by bus B => 13 seconds

To Find :

Which bus covered greater distance = ?

Which bus has greater speed = ?

Solution :

1)We know bus A covered 35m and bus B covered 39 metre(35 < 39),

Therefore,bus B travelled more than bus A.

2)We know,

$\sf{}Speed= \dfrac{Distance\ Travelled}{Time\ Taken}$

Speed taken by bus A.

$\sf{}\Rightarrow \dfrac{35m}{5s}$

$\sf{}\Rightarrow 7m/s$

Speed taken by bus B

$\sf{}\Rightarrow \dfrac{39m}{13s}$

$\sf{}\Rightarrow 3m/s$

Therefore,bus A has greater speed than bus B
