Contestants in the Run-and-Bike-a-thon run for a specified length of time, then bike for a specified length
of time. Jason ran at an average speed of 5.6 mi/h and biked at an average speed of 20.8 mi/h, going a
total of 14.6 miles. Seth ran at an average speed of 11.2 mi/h and biked at an average speed of 18.8 mi/h,
going a total of 18 miles. For how long do contestants run and for how long do they bike? Round to the
nearest hundredth if necessary,
Contestants run

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950
