Question

The world record for a woman running a marathon is approximately 2.25 hours. If a marathon's distance is 26.2 miles (42164.81 meters) and it is run

in a southeast direction, what is the velocity?
60 mph southeast
0.09 mph southeast
Omph southeast
11.6 mph southeast

Answer 1

11.6mph south east.

Answer 2

11.6mph South East

Step-by-step explanation:

Given parameters:

Time = 2.25hrs

Displacement = 26.2miles south east

Unknown:

Velocity = ?

Solution:

Velocity is the displacement divided by the time taken. It is a vector quantity with both magnitude and direction.

Now;

Velocity =
`(displacement)/(time taken)`

Velocity =
`(26.2)/(2.25)` = 11.6mph South East
