Acar is traveling at a constant speed of  45  miles per hour. how many feet does it travel in  3  seconds? remember that  1  mile is  5280  feet.

First you can convert 45 miles per hour to feet per hour:

45 × 5,280 = 237,600 feet per hour

Now you must remember that there are 60 minutes in an hour, and 60 seconds in a minute. So you can divide 237,600 feet per hour by 60 to get feet per minute:

237,600 ÷ 60 = 3,960 feet per minute

Now you just have to divide 3,960 by 60 again to get feet per second:

3,960 ÷ 60 = 66 feet per second

Now you know how fast the car can travel (in feet) in a second. So to work out how many feet it travels in 3 seconds, you just have to multiply 66 by 3:

66 × 3 = 198 feet

Therefore your final answer is 198 feet :)

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.

answer: c

because if you look at the chart you can see a pattern and compare it to the question he simplify out your

but i think the formula is f(x)=6x
