Two cars leave town at the same time going in opposite directions. One travels 44 mi/h and the other travels 47 mi/h. In how many hours will they be 69 miles apart?
44+47 = ? mi/h
time = 69/speed
sir damon plz help me in my question the probability i dont understand thanks screw down
I worked it out in the way you are probably used to. Scroll down
To find out how many hours it will take for the two cars to be 69 miles apart, we can use the formula:
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.
