Puala and kelly are comparing their ruining times. puala completed a 10-mile run in 65 minuets. kelly completed 10-kilometre run in 40 minuets. given that 8 kilometre are equal to 5 miles, whch girl has the greatest average speed?

If 8 km equals 5 miles then that means Paula ran 16 kilometers in 65 minutes.

And we already know that kelly  ran 10 kilometers in 40 minutes

do 40/10 which is 4 and 65/16 which is 4.062

Therefore Paula had the greatest average speed

what is the question? i am guessing you are looking for the area.

to find an area, you have to do length x width.

in this case, it would be 12 ft x 4 ft = 48 sq. ft
