Answer:
d) (3, 4), (5, 5), (5, 2)
Step-by-step explanation:
<em></em>
<em>We are asked to determine which orderpair in the option has the range of {2,4,5}</em>
Using the definition of range:
The range of a function is the complete set of all possible resulting values of the dependent variable (y, usually), after we have substituted the domain.
So in the given options if we write the relation in the form of (x,y) then 4, 5, 2 are the values in the range
Since distance equals speed times time (d = st), we have
t = d/s
where d = 120 miles and s = 15 miles per hour
t = d / s
t = 120 / 15
t = 8
It will take 8 hours to drive 120 miles at a speed of 15 miles per hour.
The minimum speed will be calculated as follows:
Time taken from Toledo to Elkhart=(8.15-5.45)=2 1/2 hours
Distance=136 miles
thus the speed between Toledo and Elkhart= 136 miles/2.5=54.4 mph
Distance between Toledo and Chicago is 244 miles
Distance between Elkhart and Chicago=244-136=108 miles
time taken to travel between Elkhart and Chicago assuming that I left Elkhart at exactly 8:15 and reach at 10.30:
=10:30-8:15=2.25 hours
thus the speed will be:
speed=(108)/(2.25)=48 mph
Thus for us to get to Chicago by 10:30 a.m we should drive at 48 mph
