Question

A nurse infuses a dose in 50 minutes. She needs to infuse the dose at a 20% faster rate. How much time does she need ?

Answer 1

Answer: She would need 40 minutes to infuse a dose.

Step-by-step explanation:

Since we have given that

Number of minutes a nurse takes to infuse a dose = 50 minutes

Rate faster by 20%

So, if the initial rate = 100%

After increasing the rate,

rate becomes 100%-20% = 80%

So, Number of minutes taken to infuse a dose now is given by

$\dfrac{80}{100}\times 50\\\\=0.8\times 50\\\\=40\ minutes$

Hence, she would need 40 minutes to infuse a dose.
