What’s the constant of proportionality in this story? For four hours I drove an average of about 60mph and made it 240 miles. i don't understand

9514 1404 393

  60 mph, or 4 h

Step-by-step explanation:

In the relationship between distance, speed, and time, we find that distance is jointly proportional to speed and time. That means, the equation of proportionality can be written two ways:

  distance = speed × time

  distance = (60 mph) × time . . . . . 60 mph is the constant of proportionality

or ...

  distance = time × speed

  distance = (4 h) × speed . . . . . 4 h is the constant of proportionality

Usually, we take time to be the independent variable, so the first version applies. However, the second version is also a legitimate answer.

correct answer:

i^31 = -i

-12 > a

step-by-step explanation:

-11 > 1 + a

subtract 1 from each side

-11 -1> 1 -1+ a

-12 > a
