hello

this question relates rates and we can easily work around this

$\begin{gathered} \text{since they're directly proportional to each other} \\ 41\operatorname{km}=92.87 \\ 155\operatorname{km}\text{ = x} \\ \text{cross multiply and make x the subject of formula} \\ 155*92.87=41* x \\ 14394.85=41x \\ x=351.09 \end{gathered}$

the cost of the taxi fare at a distance of 155km is $351.09
