To calculate the time (T):
$$T = \frac{D}{S}$$
Where:
Mph to hours is not a direct conversion as they measure different things. Mph stands for miles per hour and it is a unit of speed, indicating the number of miles traveled in one hour. On the other hand, hours is a unit of time.
Let's assume the following values:
Using the formula:
$$T = \frac{120}{60} = 2$$
The time to travel 120 miles at 60 mph is 2 hours.
Let's assume the following values:
Using the formula:
$$T = \frac{150}{50} = 3$$
The time to travel 150 miles at 50 mph is 3 hours.
