We know from physics class that the formula for distance of
a linear motion is given as:
d = v t
Where,
d = distance travelled
v = average velocity
t = time it took to reach the destination
Since the distance going to the office and back is just
similar, therefore we can simply equate the two:
v1 t1 = v2 t2
Where 1 signifies going to the office and 2 signifies going
back from the office. Therefore this yields to:
v1 * 5 hours = 65 mph * 4 hours
v1 = 52 mph
<span>Answer: The average
speed going to the office is 52 mph.</span>
(x+4)(x-4) =0
x +4 = 0
x = -4
x - 4 =0
x = 4
answers , x = -4 and x=4
Answer:
x=36
Step-by-step explanation:
5x=180
x=180/5=36
If r is the cost of repairs, then the inequality is:
r > 50
