Ques:- For a motorist there are three ways going from City A to City C. By way of bridge the distance is 20 miles and toll is $0.75. A tunnel between the two cities is a distance of 10 miles and toll is $1.00 for the vehicle and driver and $0.10 for each…

Asked In :- Xobin, Altran Group, Raam Group, Altorum Leren, Powercor Australia, BizSol Technologies, GFT, Marolix Technology Solutions, dnata, extreme networks,

Right Answer:
The total cost and distance for each route are as follows:

1. **Bridge**: 20 miles, $0.75 toll.
2. **Tunnel**: 10 miles, $1.00 toll for vehicle and driver, plus $0.10 for each additional passenger.

To determine the best option, calculate the total cost for the tunnel based on the number of passengers.

If there are no additional passengers, the tunnel is cheaper and shorter. If there are more passengers, the total cost for the tunnel may increase.

The bridge is a fixed cost of $0.75 for any number of passengers.

Choose the route based on the number of passengers traveling.
