44+47 = ? mi/h
time = 69/speed
time = 69/speed
Distance = Rate * Time
Let's call the time it takes for the cars to be 69 miles apart as 't' hours.
For the first car traveling at 44 mi/h, the distance it covers in 't' hours would be 44t.
Similarly, for the second car traveling at 47 mi/h, the distance it covers in 't' hours would be 47t.
Since the two cars are moving in opposite directions, the total distance between them would be the sum of the distances covered by both cars.
So, we can set up the equation:
44t + 47t = 69
Simplifying the equation gives us:
91t = 69
Now, to solve for 't', we divide both sides of the equation by 91:
t = 69 / 91
Evaluating this gives us:
t ≈ 0.7582 hours
Therefore, it will take approximately 0.7582 hours (or about 45.5 minutes) for the two cars to be 69 miles apart.
