If a car travels 60 miles in an hour, how long will it take to travel 120 miles?

To determine how long it will take to travel 120 miles at a speed of 60 miles per hour, you can use the formula for time, which is:

Time = Distance / Speed.

Here, the distance is 120 miles and the speed is 60 miles per hour. Plugging these values into the formula gives:

Time = 120 miles / 60 miles per hour = 2 hours.

This calculation clearly shows that it will take 2 hours to cover 120 miles at the given speed. The other options do not align with this calculation; for instance, 1 hour would imply traveling only 60 miles, while 3 and 4 hours would exceed the time necessary to cover the distance at the stated speed. Thus, the correct answer precisely matches the formula applied.
