Question

You traveled 52 miles. Then, your avg rate is 12 mph. What algebraic exp. models the distance?

Answer 1

12x srry if I'm wrong I'm not sure

Answer 2

Answer:

The algebraic exp. for the distance is:

Total distance = average speed × total time taken

Step-by-step explanation:

• Average speed: Average speed is the ratio of total distance and total time taken to cover that distance.

       So, average speed = $\frac{Total distance covered}{total time taken}$ .

       The SI unit of average speed= m/s.

• Distance: Distance means the length between any two points.

        The general expression of distance = final position - initial position.

 But, here we have to use the expression for distance by using average speed. So Total distance = average speed × total time taken.

• Given, distance covered = 52 miles

        Average speed = 12 miles/hour

       Total time taken = $\frac{total distance}{average speed}$ = 52/12 = 4.33 hr
