Joe is going to travel to dallas. he lives 320 miles away and can average 69 miles per hour. use an equation to represent the distance d from dallas in terms of h, the number of hours joe has traveled.
a.
d = 69h
c.
d = 320 + 69h
b.
d = 320 - 69h
d.
d = 320h + 69

D = 69h

Step-by-step explanation:

Given : Joe is going to travel to Dallas. He lives 320 miles away and can average 69 miles per hour.

To Find: Use an equation to represent the distance D from Dallas in terms of h, the number of hours Joe has traveled.

Solution :

Let distance be D

His speed is 69 miles per hour

He took h hours to cover D distance

formula: Distance = Speed*Time

Putting the given values in formula

⇒ D = 69 h

Thus Option a is correct : D = 69h

c. (0.6,-1.4)
