Cheryl is driving to her grandmother’s house for the weekend. She drives at a constant speed of 60 miles per hour on the freeway. Time (Hours) 1 2 3 4 5 Distance (Miles) What are the five values that complete the Distance (Miles) row of the table? Is this relation a function? Explain your reasoning.

Respuesta :

Answer:

ok so think about it.

shes going to her grandmas- and she travels 60 miles for every hpur she drives.

time(hours):

1 shes driving 60 miles PER HOUR- so in one hour she traveled 60. (60 is answer)

2 shes driving 60 mies per hour- so two hours would be 120. (120 is answer)

3 shes driving 60 mies per hour- so 3 hours would be 180 (this means 180 is answer)

4 shes driving 60 mies per hour- so 4 hours would be 240 (and so 240 is answer)

5 shes driving 60 mies per hour- so 5 hours would be 300 (300=the answer)

Step-by-step explanation:

so you kinda just wannamu.Mutiply the distance per hour by the hours... so like- 60 mph*1=60 60 mph*2=120 etc.

the answers are

1:60

2:120

3:180

4:240

4:300

Answer:

Givens:

  • [tex]s=60\frac{mi}{hr}[/tex]

We have to ding each distance at those given times to complete the table. We can solve it by just replacing values into the constant movement definition, which is [tex]d=st[/tex]

For [tex]t=1[/tex]:

[tex]d=60\frac{mi}{hr} (1hr)[/tex]

[tex]d=60mi[/tex]

For [tex]t=2[/tex]:

[tex]d=60\frac{mi}{hr} (2hr)[/tex]

[tex]d=120mi[/tex]

For [tex]t=3[/tex]:

[tex]d=60\frac{mi}{hr} (3hr)[/tex]

[tex]d=180mi[/tex]

For [tex]t=4[/tex]:

[tex]d=60\frac{mi}{hr} (4hr)[/tex]

[tex]d=240mi[/tex]

For [tex]t=5[/tex]:

[tex]d=60\frac{mi}{hr} (5hr)[/tex]

[tex]d=300mi[/tex]

Therefore, the complete table would be:

t      d

1     60

2    120

3    180

4    240

5    300

We conclude that the table represent a function, because it's defined the relation between two variables, one independent (time), one dependent (distance). But, the most important characteristic is that for every t-values, there's only one d-value, and that is the definition of a function.
