Question

A mill sail whose length is 540cm makes 10 revolutions per minute. What distance does it end travel in an hour?

Pls ans...

Answer 1

Number of revolutions made by the mail sail = 10

Length of the mail = 540 cm.

Total distance covered by the mail sail in 10 revolutions per minute = 540 × 10

= 5400 cm.

Now,

∵ Distance covered in 1 minutes is 5400 cm.

∴ Distance covered in 60 minutes (1 hrs) is 60 × 5400 = 324000 cm.

Hence., the total distance covered by the mail sail in 1 hrs is 324000 cm.

Hope it helps.

Answer 2

Given length of a mill sail = 540 cm.

Given that it makes 10 revolutions per minute.

Distance covered by mill sail in 1 minute = 5400 * 10

= 5400 cm.

Distance covered by mill sail in 60 minutes = 5400 * 60

= 324000 cm.

Hope it helps!
