A car travels 2.5 hours in a northerly Direction for 300 KM. what is the speed and velocity
STatiana [176]
Speed is distance traveled per block of time. As an equation, this is 
Speed = distance/time

In your problem, the given distance is 300km, and the time is 2.5 hours.
Plugging into the equation,
Speed = 300km / 2.5 h
Speed = 120 km/h

Velocity is speed <em>and</em> direction. 
The velocity would be 120 km/h north.

100 POINTS!! Express in radical form.
Vilka [71]

Answer:

27   4th root (x^3)

Step-by-step explanation:

(81x) ^ 3/4

We know (ab) ^c = a^c b^c

81 ^ (3/4)  * x^3/4

We can rewrite 81 as 3^4

(3^4)^(3/4)  * x^3/4

We know that a^b^c = a^ (b*c)

3^(4*3/4)  * x^3/4

3^(3) * x^3/4

27  * x^3/4

27   4th root (x^3)
