Given :

• As per given in the

question,A man covered 80 kilometers distance in 4 hours time.

As we know that if distance and time is given then we have to find out the value of speed. So let's find!

Using formula :

Distance

Speed =

=

Time

Denote Distance by 'D' Speed by 'S' and Time by 'T'as given in the question.

Now substitute the values which

we are given with...

d S=

80 S =

4

km

s= 20

hr

Hence, Speed of the man is 20km/hr respectively.

Since we know that,for converting km/hr into m/sec we use this trick

km 20-

hr

5 m 20 x

18 sec

50 m

=

-

9 sec

Hence,it is converted and it's value is 50/9 m/sec.
