Ferdinand went from place A to place B and from there to place C. A is 7.2 km from B, and B is 11.7 km from C. Albert went from place A to place D and from there to place C. D is 9.1 km from A and C is 10.8 km from D. Who traveled more and by how much?

Correct answer:

x = A
d =  1 km

Step-by-step explanation:

AB=7.2 km BC=11.7 km  F=AB+BC=7.2+11.7=10189=18109=18.9 km  AD=9.1 km DC=10.8 km  A=AD+DC=9.1+10.8=10199=19109=19.9 km  A > F  x=A
d=AF=19.918.9=1 km
