Question

A hyena can run one over four of a mile in 22.5 seconds. At this rate, which equation can be used to determine how fast a hyena runs in miles per hour?

one-fourth mile over twenty-two point five seconds = 40 miles per hour
twenty-two point five seconds over one-fourth mile = 40 miles per hour
one-fourth mile over twenty-two point five seconds = 90 miles per hour
twenty-two point five seconds over one-fourth mile = 90 miles per hour

Well there are two parts to the question. The concept and the implementation. The concept is pretty simple. The beginning asks you whether you should put the 22.5 over the .25 or vice versa. Since what you are trying to find is the speed, it would be \[\large \sf Speed=\frac{distance}{Time}\] I'll leave it to you to figure which one is the distance and which one is the time.

The implementation is a bit more complicated. You want to stay with the formula \[\large \sf S=\frac{d}{t}\] (The same formula as the one up there) but since you are in seconds you have to convert the seconds to hours.

Answer 12

Hmm, im still a little confused

Answer 13

Basically find out how many times 22.5 seconds goes into an hour (aka 3600 seconds) and then multiply d/t by that.
