Step 1: Write equation
a = (b - 4)/c
Step 2: Multiply both sides by <em>c</em>
ac = b - 4
Step 3: Add 4 on both sides
ac + 4 = b

Answer:
Average speed is 48 km per hour
Step-by-step explanation:
A student drove to the university from her home and noted that the odometer reading of her car increased by 16.0 km. The trip took 20.0 min. (a) What was her average speed? in km/hr
Distance traveled is 16 km and the time taken is 20 minutes
convert minutes into hour. to convert minutes into hour we divide by 60 because 1 hour = 60 minutes

so time = 1/3  and distance = 16
Average speed = distance by time

Average speed is 48 km per hour
 
        
             
        
        
        
Simple interest is basically the cost of borrowing money over a period of time.  So if you have borrowed $110.00 at 5% for two years, you will multiply the 5% by the two years (presuming that it is 5% annual percentage rate (APR).  So, You will multiply the 110 by 10% (or .1) to get $11 dollars of simple interest.
