Question 1122491: Jose is 10 feet from a mailbox when all of a sudden he begins walking directly away from the mailbox at a constant speed of 4 feet per second.
a. How far is Jose from the mailbox 5 seconds after he started walking?
b. Write a formula that expresses Jose's distance from the mailbox (in feet),
d, in terms of the number of seconds t since he started walking. (Hint: it might help to start with drawing a diagram of the situation.)
c.As Jose walks away from the mailbox, is his distance from the mailbox proportional to the time elapsed since he started walking away from the mailbox?

You can put this solution on YOUR website! Jose is 10 feet from a mailbox when all of a sudden he begins walking directly away from the mailbox at a constant speed of 4 feet per second.
:
a. How far is Jose from the mailbox 5 seconds after he started walking?
(5*4) + 10 = 30'
:
b. Write a formula that expresses Jose's distance from the mailbox (in feet),
d = (t*s) + 10; where
d = distance
t = travel time
s = speed
d, in terms of the number of seconds t since he started walking.
d = 4t + 10
:
c.As Jose walks away from the mailbox, is his distance from the mailbox proportional to the time elapsed since he started walking away from the mailbox?
Yes, directly proportional
