<span>1 hour 36 minutes = 1 36/60 = 1 3/5 = 1.6 hours
Speed of car leaving wallace be x mph
Speed of car leaving vernonville will be ( x+10) mph
1.6 ( x + x+10) = 192
2x + 10 = 120
2x = 110
x = 55
ANSWER Wallace car = 55 mph Vernonville = 65mph
Therefore, </span><span>the average speeds of both cars are 55 mph for the Wallace car and 65 mph for the Vernonville.
I hope my answer has come to your help. Thank you for posting your question here in Brainly.</span>
2.22 m/s. Average speed is Total distance over time it took. 100m/45s = 2.22m/s
What is horoscope?
A forecast of a person's future, typically including delineation of character and circumstances, based on the relative positions of the stars and planets at the time of that person's birth.
*A short forecast for people born under a particular sign, especially as published in a newspaper or magazine.
*A birth chart.
What is its uses?
It can also be calculated for an event, a question, and even a country. Symbols are used to represent planets, signs, and geometric connections called aspects. In most cases, the horoscope in Western astrology is drawn on a circular wheel.
The instantaneous velocity is how the position is changing with respect to time in a specific point in time, as opposed to the average value given by Delta(x)/Delta(t). It's given by taking a limit of Delta(x)/Delta(t) where t approaches 0, that is, by derivating x(t) in respect to t.
v(t) = x'(t) = (28 + 12.4t + 0.045t^3)' = 12.4 + 0.135t^2
But we want to find the velocity at t = 8s:
v(8) = 12.4 + 0.135*(8)^2 = 21.04m/s
