The length of a rectangle is 2 more than three times the width. the area of the rectangle is 161 square inches. what are the dimensions of the rectangle? if x = the width of the rectangle, which of the following equations is used in the process of solving this problem? 2x^2 + 3x - 161 = 0 3x^2 + 2x - 161 = 0 6x^2 - 161 = 0

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
