If a person walks 1/2 of a mile 1/4 of an hour at what speed do they walk in miles per hour?

2 miles.

Step-by-step explanation:

We can use proportions!

1/2 mile =    x    

1/4 hour   1 hour

Since you can multiply 1/4 by 4 to get 1 hour, multiply 1/2 by 4 to get two miles. Therefore, x = 2, so the person walks at a speed of two miles per hour.

answer 2 mph

Step-by-step explanation:

speed= distance/ time

s=.5/.25=2

step-by-step explanation: noo

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
