Answer:
13.63 miles per hour
Step-by-step explanation:
100 yards / 15 sec converted to miles per hour
<u>100 yards</u> x <u> 60 sec</u> x <u> 60 min</u> x <u> 1 mile </u> = 13.63 miles/hr
15 sec 1 min 1 hr 1760 yards
the mistake on Mrs Dukes is the conversion from miles to yards.
1 mile = 1760 yards NOT 5280 yards
No because she can run slow and waste time and not get that far and it will be 3 min. But if you go fast and stop at the same distance it won’t take as long because of your SPEED.
Since the equation for solving circumference is 2

r, you can see that 2

r = 46. Dividing 2

on both sides will give you r, or the radius.
