Which runner has the higher velocity?

runner #38

distance: 3.2 miles

time: 24 minutes, 28 seconds

runner #103

distance: 3.2 miles

time: 24 minutes, 22 seconds

question 47 options:

runner #38

runner #103

they have the same velocity

none of the above

They have the same velocity.

Explanation:

In order to know the answer, we have to consider using the formula for  "velocity."

Velocity refers to the speed that an object has according to a given direction.

1. We'll have to get the velocity of Runner #38 first.

displacement = 3.2 miles

time= 24 minutes, 28 seconds

Let's convert 28 seconds to minutes: 28 sec. × = 0.47 minutes

So, 24 minutes, 28 seconds is the same with 24.47 minutes

Let's compute for the velocity.

v = = 0.13 (this is the velocity of Runner #38)

2. Next, we have to get the velocity of Runner #103 in order to compare them.

displacement = 3.2 miles

time = 24 minutes, 22 seconds

Let's covert 22 seconds to minutes: 22 sec. × = 0.37 minutes

So, 24 minutes, 22 seconds is the same with 24.37 minutes

Let's compute for the velocity.

v = = 0.13 (this is the velocity of Runner #103)

Thus, we can conclude that "they have the same velocity."

be confident on yourself. ignore such fools and move on ; )
