Annette rode her bike 6.8 miles at a constant rate for 90 minutes. To find how fast she traveled, she solved the equation 6.8= x⋅90. What does x represent?

a)The total distance after x minutes

b)Her speed in miles per minute

c)The amount of time it takes to travel 6.8 miles

d)The number of miles she has traveled so far

X represents her speed in miles per minute (b). To find her speed she would divide distance by time. If you divide 6.8 miles by 90 minutes and solve for x you will be finding her speed

Answer:

x represents Annette speed in miles per minute. Hence, option b) is correct.

Step-by-step explanation:

Given that Annette rode her bike 6.8 miles at a constant rate for 90 minutes. Also to find how fast she traveled, she solved the equation \(6.8=x\times 90\). Now, we have to tell here what x represents.

As, \(Speed=\frac{Distance}{Time}\)

Let speed of bike is x miles/min and given distance is 6.8 miles and at a constant rate for 90 minutes.

∴ \(x=\frac{6.8}{90}\)

⇒ \(6.8=x\times 90\)

which is the same equation as given.

Here x represents Annette speed in miles per minute. Hence, option b) is correct.
