The perimeter of a rectangular sports court is 134 feet. after a game, a player's coach estimates that the athlete has run a total of 378 feet, which is equivalent to four times the court's length plus nine times its width. what are the dimensions of the sports court?

45ft by 22ft

Step-by-step explanation:

perimeter is 2L+2W =134ft

The coach says that 378=4L+9W

We can rearrange the first equation to get L=67-W, then solve by substitution.

378=4(67-W)+9W=268+5W

110=5W so W=22

L=67-W and W=22 so

L=67-22=44

Therefore the dimensions are 22 by 45

right

step-by-step explanation:

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
