How did katherine johnson’s work in math affect us today?

Step-by-step explanation:

NASA research mathematician Katherine Johnson is photographed at her desk at Langley Research Center in 1966. Johnson began her career in 1953 at the National Advisory Committee for Aeronautics (NACA), the agency that preceded NASA, one of a number of African-American women hired to work as "computers" in what was then their Guidance and Navigation Department, just as the NACA was beginning its work on space. Johnson became known for her training in geometry, her leadership, and her inquisitive nature; she was the only woman at the time to be pulled from the computing pool to work with engineers on other programs.

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m

answer: yard ramps with a level off platform are typically 36 feet long. truck, rather than at an angle, enabling access to those pallets at the very back of the truck. if you are using your yard ramp to convert a loading dock into a drive-in door, we even at 60 inches (5 feet) high and a 30 foot ramp, the slope of the ramp will be less
