GIVEN :

• A man walks 8km in 1 hour 20 minutes

TO FIND :

• Speed of the man.

SOLUTION :

Main points :

• 1 hour = 60 minutes
• 1 hour 20 minutes = 60 + 20 minutes
• 1 hour 20 minutes = 80 minutes

• 1 kilometer = 1000 metre
• 8 kilometer = 8000 metre

So, the man's speed is 8000 metres per 80 minutes.

So the man's speed in 1 minute

$So \: the \: man's \: speed \: in \: 1 \: minute = \frac{8000}{80} \\ = 100 \: metre$

Speed per hour = 100 × 60 metres

= 6000 metres

• 6000 metres = 6 kilometers
