The formula d=rt gives the distance traveled for a rate r and an amount of time t. A ship travels at a rate of 10 miles per hour for 2 hours.

What distance did the ship travel?

A. 5 miles

B. 12 miles

C. 20 miles

D. 102 miles

c

Step-by-step explanation:

it goes 10 miles per hours

and it goes for 2 hours

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
