•225/4 =

•56.25 which means 56 mins 25 secs as answer

Answer 2

56.25 minutes are required to work.

Step-by-step explanation:

Since we have given that

Number of minutes = 45

Degree = 60°

if the degree = 75° C

According to question,

$\dfrac{45}{60}=\dfrac{x}{75}\\\\\dfrac{3}{4}=\dfrac{x}{75}\\\\\dfrac{3\times 75}{4}=x\\\\\dfrac{225}{4}=x\\\\x=56.25\ minutes$

Hence, 56.25 minutes are required to work.
