The average speed is 8 miles/hour
Step-by-step explanation:
The course is 2/5 of a mile long, this means it is 0.4 miles long.
Distance covered in 4 laps will be ; 4×0.4=1.6 miles
Time taken to cover the four laps = 12 minutes = 12/60 hours = 0.2 hrs
Average speed = Distance/ time
Average speed = 1.6/0.2 = 8 miles/hour

The expression (2m^4)^3is an algebraic expression, and the simplified value is 8m^12
<h3>How to simplify the algebraic expression?</h3>
The expression is given as:
(2m^4)^3
Expand the bracket
(2m^4)^3 = 2^3 * m^(4 * 3)
Evaluate the exponents
(2m^4)^3 = 8 * m^12
Evaluate the product
(2m^4)^3 = 8m^12
Hence, the simplified value is 8m^12

If 12 = 2y, then y = 6. To solve this kind of equation, whatever you do to one side of the equation, you must do to the other, and it will remain equivalent. If you divide both sides by 2, you get 6 = y. Also, 2 * 6 = 12, a much easier way to find the answer.
