It takes (68 hours) divided by (the speed you travel, in miles per hour).
We can solve this problem using the concept of speed. We know the speed: The information states that it takes 2 hours to travel 90 miles. Therefore, the speed is 90 miles / 2 hours = 45 miles per hour. Now, we need to find the distance with a different travel time: You want to know how far you can travel in 7 hours with the same speed of 45 miles per hour. Use the formula: Distance = Speed × Time Plug in the known values: Distance = 45 miles per hour × 7 hours = 315 miles Therefore, if it takes 2 hours to travel 90 miles at a constant speed of 45 miles per hour, you can travel 315 miles in 7 hours with the same speed.

distance divided by time... For example, if it takes 2 hours to travel 4 miles, your velocity is: 4 miles/2 hours = 2 miles/hour
