B=30min

Answer 2

To determine the value of "d" in your equation, we can use the information that 90% of "d" is equal to 1 hour.

Let's set up the equation:

0.9d = 1 hour

To find the value of "d," we need to isolate it on one side of the equation. We can do this by dividing both sides of the equation by 0.9:

0.9d / 0.9 = 1 hour / 0.9

Simplifying, we have:

d = 1.1111... hours

Therefore, 90% of "d" is equal to 1 hour when "d" is approximately 1.1111 hours.
