Find the value of b: 14:45 = 3b : 63?

To find the value of b, we can set up a proportion:

14:45 = 3b : 63

First, convert the time 14:45 to minutes:

14 hours * 60 minutes/hour = 840 minutes
840 minutes + 45 minutes = 885 minutes

Now, we can set up the proportion:

885 / 63 = 3b / 63

Solving for b:

885 = 3b
b = 295

Therefore, the value of b is 295.

14:45 = 3b : 63

Step 1: Cross-multiply
14 × 63 = 45 × 3b

Step 2: Solve for b
882 = 135b
b = 882 / 135
b = 6.53
