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) 70 greater-than 7 minus 55 70 less-than t minus 55 70 less-than-or-equal-to t + 55 70 greater-than t + 55

70>t+55

Step-by-step explanation:

The way you wrote the options were somewhat confusing.

She is looking to beat her time, so we are looking at one that is 70> because the new time must be below 70

Since she has already ran 55 minutes, we're looking at her remaining time she still has to run for

We could suppose t is the remaining time left, so 70>t+55

what "following statement"?

step-by-step explanation:

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.
