Question

2. Maryse went for a bike ride. She rode at a constant speed, an she traveled 7 miles in one hour.Maryse wrote the equation y=7x to model her bike ride, where x is the time Maryse spent riding,and y is the distance she traveled.a. Maryse uses her equation to estimate that she rode 14 miles in the first two hours of her trip.Did she use her equation correctly? Explain why or why not. Ensure to write the equation withthe appropriate numbers plugged in.b. Maryse uses her equation to predict that she would travel 40 miles if she rode for four hours.Did she use her equation correctly? Explain why or why not.

Answer 1

1.) YES! Maryse used her equation correctly.

2.) NO! Maryse did not use her equation correctly.

Step-by-step explanation

Given:

A bike ride model: y = 7x

where:

1). x is the time Maryse spent riding,

2). y is the distance she traveled

Now, she rode 14 miles in the first two hours of her trip

That is:

y = 7x

where y = 14 miles and x = 2 hours

14 = 7(2)

14 = 14

She indeed used her equation correctly.

When she predicted that she would travel 40 miles if she rode for four hours.

That is:

y = 7x

where y = 40 miles and x = 4 hours

`\begin{gathered} 40\text{ }\\e\text{ 7\lparen4\rparen} \\ 40\\e28 \end{gathered}`

Hence, She indeed used her equation correctly in part one but she did not use her equation correctly in part two.
