Answer:
1. The total distance will be equal to 20 miles plus the remaining distance which would be obtained when you multiply the speed to time t. The equation would be written as follows:
120 = 20 + 50t
2. The minimum time would be 0 hours. The maximum time is when the total distance of 120 is fully covered.
t ≤ (120 - 20)/50
t ≤ 2 hours
Thus, the domain would be 0 < t ≤ 2.

Answer:
1 First blank; f(1.5)=95 2 Blank; 1.5 3 Blank; 95
Step-by-step explanation:
you use the equation f(x)=50x+20 and put 1.5 in
f(1.5)=50(1.5)+20 = f(1.5)=95
you get 95, and that is the number of miles
1.5 is number of hours
