Answer 2

Answer:

The charge of internet cafe is 120 Rs/Hour.

Step-by-step explanation:

Charge of 45 minutes = 90 Rs

Charge of 1 minute = $\dfrac{90}{45}$

Charge of 1 minute = 2 Rs

We know that-

One hour = 60 minutes

So, charge for 60 minutes = 2 × 60

Charge for 60 minutes = 120 Rs

Hence the charge of internet cafe is 120 Rs/Hour.
