Question

A snail travels 820 mm in 0.75 minutes. What was his speed in m/s?

Answer 1

speed in m/s=0.01822 metre/s

Explanation:

Conversation rate of mm to m is

1000 mm = 1 metre

820 mm= 820/1000

829 mm= 0.82 metres

Conversation rate of minutes to second

I minute = 60 seconds

0.75 minute = 60*0.75 seconds

0.75 minute= 45 seconds

speed in m/s= 0.82 metres/45 seconds

speed in m/s= 0.82/45

speed in m/s=0.01822 metre/s
