Question

Jose is going to drive from his house to City A without stopping. Jose plans to drive at

a speed of 25 miles per hour, and after driving for 3 hours, he will be 25 miles away
from City A. Write an equation for the function D(t), representing Jose's distance
from City At hours after leaving his house.

Answer 1

25(s)

s= the number of hours

Explanation:

25(s)

answer would be 25(3) = 75 miles.

75+25= 100 miles

so the distance from Jose's house to City A is 100 miles

Answer 2

Answer:D(t) = 100 - 25t

Explanation:

Distance travelled = speed × time

Jose plans to drive at

a speed of 25 miles per hour and he drove for three hours. It means the the distance that Jose covered in three hours would be

25 × 3 = 75 miles

After driving for 3 hours, he will be 25 miles away from City A.

This means that the total distance from city A is 75 + 25 = 100 miles

Let D(t), represent Jose's distance

from city A, t hours after leaving his house. Therefore,

D(t) = 100 - 25t
