Question

The speed of blood in capillaries is 1mm/min how will it be converted into m /sec?

Answer 1

`0.000016667` m/sec or `1.6667xx10^-5`m/sec

Explanation:

Given speed of blood = `1`mm/min
To convert this speed to `m/sec` we need to convert `mm` to `m` and `min` to `sec`

The relationship between m and mm is `1m` = `1000mm`
therefore, `1mm` = `1/1000 m` = `0.001m`...........(A)

Now, for time, `1min` = `60 sec`.........................(B)

So, `1`mm/min can be written as:

`(0.001m)/(60sec)` (By using values from A & B)

which is, `0.000016667`m/sec and it can be also written as:
`1.6667xx10^-5` m/sec
