Answer:
Explanation:
A bicyclist travels at a constant speed of 18 miles per hour for a total of 27 minutes
Using x to represent domain and
y to represent distance traveled
Domain (x) is number of hours used
Range (y) is distance traveled
speed = 18 miles per hour
time = 27minutes = 0.45hours
Since 60 mins makes 1hour
Therefore, 27mins will make x hour
X hour =27mins/60mins
X hour=0.45hours for 27mins
Distance = speed × time
Distance = 18 ×0.45= 8.1miles
Number of hours( x) used is from 0 to 0.45 hours
So domain which is the number of hours uses is 0 to 0.45hours
Range which is distance travelled is 0 to 8.1 miles
