Answer 1

Given :

A 18​-mile taxi ride takes 21 minutes and costs ​$12.60.

To Find :

The cost of a 39​- mile taxi ride. What unit price do you​ need.

Solution :

Unit price per mile :

`p=(12.60)/(18)\\\\p = \$0.7\ /mile`

Cost of 39 mile taxi ride :

`C = 39* p\\\\C=39* 0.7\\\\C=\$27.3`

Therefore, unit price is $27.3 and unit price is $0.7 / mile .

Hence, this is the required solution.
