Answer:
Step-by-step explanation:
1.
in the first hour they traveled fast
in the first hour they traveled 16 units
in the second hour they traveled 10 units
in the third hour 14 units
in the fourth hour 12 units.
2.
\[domain:{0≤x≤4}\]
3.
f(2)=10(2-1)+16=10+16=26
f(2) means distance in 2 hours.
4.
f(3)=14(3-2)+26=40 units.
5.
total distance traveled=12(4-3)+40=52
