A pony in a pony ride takes 42 seconds to make one circuit around a circle. The circumference of a circle is 84 m. What is the average speed of the pony in meters per second?

Average speed = 2 m/s

Step-by-step explanation:

speed = distance / time

speed = 84 m / 42 sec

speed = 2 m/s

the answer is 200

step-by-step explanation:

the way the question is worded, it seems to imply the $264 interest is simple interest, not compound interest.

the simple interest for 2 years is $264; the simple interest for 1 year is $132.

$132 interest on a $600 investment means an interest rate of (132/600)*100 = 22%.

the value of $200 at 22% interest compounded annually for three years is

200%281.22%29%5e3

the amount of interest is that value, minus the original $200.
