the time, t, required to drive a certain distance varies with the speed, r. if it takes 7 hours to drive the distance at 55 miles per hour, how long will it take to drive the same distance at 65 miles per hour?
We can use the formula:
time = distance / speed
Let's call the distance "d".
At 55 miles per hour, it takes 7 hours to travel the distance:
7 = d / 55
We can solve for "d" by multiplying both sides by 55:
7 * 55 = d
d = 385
So the distance is 385 miles.
Now we can use the same formula to find the time it takes to travel the distance at 65 miles per hour:
time = 385 / 65
time = 5.92 hours
Rounded to the nearest minute, it will take about 5 hours and 55 minutes to drive the same distance at 65 miles per hour.

You're welcome! If you have any more questions, feel free to ask.
To find out how long it will take to drive the same distance at 65 miles per hour, we can use the formula for time:
time = distance / speed
Given that it takes 7 hours to drive the distance at 55 miles per hour, we can set up the following equation:
7 hours = distance / 55 miles per hour
To find the distance, we can rearrange the equation:
distance = 7 hours * 55 miles per hour
Now, we can use the newly found distance and the speed of 65 miles per hour to calculate the time it will take:
time = distance / speed
time = (7 hours * 55 miles per hour) / 65 miles per hour
Simplifying the equation, we get:
time = 385 hours * miles / (65 miles per hour)
time = 5.92 hours
Therefore, it will take approximately 5.92 hours (or about 5 hours and 55 minutes) to drive the same distance at 65 miles per hour.
