the speed rate is simply obtained by dividing the meters by the seconds.
so Tawni did 50 meters in 40.8 seconds, that means her speed rate is 50/40.8 or about 1.23 m/s.
Pepita did 100 meters in 60.2 seconds, so she's 100/60.2 or about 1.66 m/s.
Susana did 200 meters in 112.4 seconds, so she's about 1.78 m/s.
the one who ran the fastest is the one who covered more meters in 1 second.
2(a^2 - 5b) - (c^2 - 1) =
2a^2 - 10b - c^2 + 1 <===
[A+7= 28] is the correct equation I believe, though I may be wrong.
Answer:
1- |x+3| < -5 = No solutions
2- |x+8| < 2 =x<−6 and x>−10
3- |x + 3| < 5 = x<2 and x>−8
