Answer:
since the room is rectangular and has 4 sides
2 sides have the same length
18*2= 36m
80*2=160m
then add the sums...
the answer is 196 meters
Step-by-step explanation:
2x + x = 54 wher x = number of girls
3x = 54
x = 18
18 girls
It total she would spend 65 minutes brushing the horse (this can also be 60=1 hour +5 =1 hour and 5 minutes)

The rate for 40 meters in 10 seconds is
40m/10sec (40 meters per 10 seconds)
You can turn it into a different unit of measurement by multiplication or division.
For example, if you want the rate in 1 second, you divide both units by 10 (because there are 10 seconds, and 10 ÷ 10 = 1).
40m/10sec then becomes
4m/1sec (4 meters per 1 second)
40 ÷ 10 = 4, and 10 ÷ 10 = 1
Or if you'd like it in minutes, you multiply both units by 6 (because there are 60 seconds in 1 minute, and 6 x 10 = 60).
40m/10sec becomes
240m/60sec = 240m/1min
40 x 6 = 240, 10 x 6 = 60 = 1 minute
