Emma is training for a 10-kilometer race. she wants to beat her last 10-kilometer time, which was 1 hour 10 minutes. emma has already run for 55 minutes. which inequality can be used to find how much longer she can run and still beat her previous time? (1 hr = 60 min) as fast as you can ?

x < 15

Step-by-step explanation:

Emma's previous time was 1 hour 10 minutes.  This is equal to

60+10 = 70 minutes.

She has already run 55 minutes; this means the remaining time, x, added to 55 must be less than 70 in order to beat her previous time:

x + 55 < 70

Subtract 55 from each side:

x + 55-5 < 70-55

x < 15

choice b is correct

step-by-step explanation:

we have been given the following system of linear inequalities;

we are required to graphically determine the solution to these system of inequalities. using a graphing tool, the solution is as shown in the attachment below;

squares, rhombus, rectangles
