How to calculate distance, speed and time

What will you find in this article?

The most commonly used equations in algebra are those that include distance, speed, and time. The equation relates to various tasks in real life, such as when planning a trip. Speed ​​is how fast something travels in a given amount of time. Time refers to how long it takes to travel a certain distance while moving at a certain speed. Distance is how far something travels at a certain speed and amount of time. A simple algebraic equation relates these three concepts.

Section 1

Understand the basic equation: D = v * t, where D is distance, “v” is speed, and “t” is time. If you are given a speed at which someone is traveling and the time it takes them to travel, you can use the equation to calculate the total distance traveled.

Solve a problem using the following formula. For example, if a car travels at 60 miles (96 km / h) and the trip takes 2 hours, you can easily calculate the distance traveled: Distance = 60 mph x 2 hours (or 96 km / h x 2 hours) Distance = 120 miles (192 km)

Modify the formula to calculate the time. d = v * t, you can solve for “t” and divide both sides by “v”. So the new formula would look like t = d / v. Suppose you want to know how long it would take to travel 120 miles (192 km) at a speed of 60 mph (96 km / h): Time = 120 miles / 60 mph (or 192 km / 96 km / h) Time = 2 hours

Modify the equation again to calculate the velocity. d = v * t, you can solve for “v” and divide both sides of the equation by “t” to get the formula v = d / t. Now, suppose they tell you that a car traveled for 2 hours and traveled 120 miles (192 km). A problem can query how fast the car was traveling: Speed ​​= 120 miles / 2 hours (or 192 km / 2 hours) Speed ​​= 60 mph (96 km / h)
