Answer:
90 miles
Step-by-step explanation:
There's more than one way in which to do this. I have chosen to convert '180 minutes' to '3 hours.'
Since distance = rate times time, we have here:
distance traveled in 180 minutes = (30 mph)(3 hr) = 90 miles
8/10 = 0.8
Therefore, 0.8 (8/10) is put on the number line shown below.
10.50
15x + 42y = $13 050
hope that helped :)
