Piravena must make a trip from \$A\$ to \$B\$, then from \$B\$ to \$C\$, then from \$C\$ to \$A\$. Each of these three parts of the trip is made entirely by bus or entirely by airplane. The cities form a right-angled triangle as shown, with \$C\$ a distance of 3000 km from \$A\$ and with \$B\$ a distance of 3250 km from \$A\$. To take a bus, it costs Piravena \$\\$0.15\$ per kilometer. To take an airplane, it costs her a \$\\$100\$ booking fee, plus \$\\$0.10\$ per kilometer.Determine the distance she travels for her complete trip.

find the distance   BC using pythagorean theorem

3250^2  =  3000^2  + BC^2         BC = 1250 km

SO her total distance travelled  =   3250  +  1250  +  3000 km = ......

Hint:

Use the Pythagorean Theorem, which is a^2+b^2=c^2.
