Question

horacio is cycling at a speed of -8 miles per hour;if he starts at the same zero point,what will his position be after 45 minutes?

Answer 1

Taking into account the definition of speed, Horacio's position after 45 minutes will be 6 miles.

Definition of speed

Speed ​​is a physical quantity that expresses the relationship between the space traveled by an object and the time used for it. That is, the speed is associated with the change of position of an object in space within a certain amount of time.

In other words, speed can be defined as the amount of space traveled per unit of time with which a body moves and can be calculated using the expression:

speed= distance traveled÷ time

Position of Horacio after 45 minutes

In this case, you know:

• speed= 8 miles/h
• distance traveled= ?
• time= 45 minutes= 0.75 h (being 60 minutes=1 h)

Replacing these values ​​in the speed definition:

8 miles/h= distance traveled÷ 0.75 h

Solving:

8 miles/h× 0.75 h= distance traveled

6 miles= distance traveled

In summary, Horacio's position after 45 minutes will be 6 miles.
