Question

A snail covers a distance of 100 meter in 50 hours calculate the average speed of snail in km/m
​

Answer 1

Answer:

Distance =100m =100/1000=0.1km

Time=50hrs

Speed= Distance/Time

=1/500

=0.002km/hr

Answer 2

Solution :-

Given ,

• Distance travelled by snail = 100m
• Time taken by the snail to travell = 50 hours

We need to find ,

• Average speed of snail = ?

Firstly converting hours to seconds because SI unit of speed is ‘m/s’

• 1 hour = 3600s

→ 5 hours = 5(3600)

→ 5 hours = 18000s

As we know that ,

Average Speed = Total distance/Total time

Substituting ,

• Total distance = 100 m
• Total time = 50 h = 18000s

⇒ Average speed = 100/18000

⇒ Average speed = 1/180

⇒ Average speed = 0.0055 m/s

Hence , average speed of the snail = 0.005 m/s
