The answer would be A) 2 sqrt 30x
just took test:) brainly plz maybe but A is answer
Speed = distance/time
distance = speed * time
let x = time covered by running
15 = run distance + walk distance
15 = 9(x) + 3(3-x)
15 = 9x + 9 - 3x
15 - 9 = 6x
6 = 6x
x = 1 hour
Therefore:
Running distance = speed * time
RD = 9km/hr * 1 hr
RD = 9km
160 km - 100%
100%+30%=130%
160*130%:100%=208 (km) - <span>the number sought</span>
Answer:
The same inputs cannot have multiple different outputs
