two cars start driving in the same direction from the same place. If one travels 54 mph and the other 61 mph, how long will it take to be 49 miles apart?
To find out how long it will take for the two cars to be 49 miles apart, you can use the formula:
Time = Distance / Speed
Let's calculate the time it will take for the cars to be 49 miles apart:
For the first car, traveling at 54 mph:
Time = 49 miles / 54 mph = 0.9074 hours (rounded to four decimal places)
For the second car, traveling at 61 mph:
Time = 49 miles / 61 mph = 0.8033 hours (rounded to four decimal places)
Therefore, it will take approximately 0.9074 hours (or 54.44 minutes) for the two cars to be 49 miles apart.
To find out how long it will take for the two cars to be 49 miles apart, we can use the formula: time = distance / rate.
Let's assume that the time it takes for the two cars to be 49 miles apart is t (in hours).
The car traveling at 54 mph will cover a distance of 54t miles in time t.
Similarly, the car traveling at 61 mph will cover a distance of 61t miles in time t.
Since the two cars are moving in the same direction, and we want to find out when they will be 49 miles apart, we can set up the following equation:
61t - 54t = 49
Simplifying the equation, we get:
7t = 49
Dividing both sides of the equation by 7:
t = 7
Therefore, it will take 7 hours for the two cars to be 49 miles apart.
