Question

Ella is going to drive from her house to city a without stopping. Ella’s house is 100 miles from city a and after driving three hours she will be 25 miles away from city a. Writing equation for D in terms of T represent an LS distance from city a T hours

Answer 1

Answer:
d = 100 - 25t

Step-by-step explanation:

Let's use basic logic here.
If we are 100 miles away from a place, and we've got 25 miles to go, we've already travelled 75 miles.
Since we've travelled 75 miles in 3 hours, then we travel at a rate of 75 divided by 3 = 25 miles per hour.

The distance to City A will be represented as 100 - miles already travelled. We can find how many miles have been travelled by multiplying 25 by t, the amount of hours we've spent driving.

This creates the equation d = 100 - 25t
Hope this helped!
