Charra [1.4K]
Speed=distance / time  ⇒ distance=time x speed
distance=d
time=t
speed= s

d=s*t

Distance  traveled by Mr Guerrero, when his daugther left the house
Data:
s=40 miles/ hour
t=2 hours
d=40 miles/ hour * 2 hours=  80 miles

Total distance traveled by Mr Guerrero:
d=80 miles + 40 miles/hourt    ⇒d=80+40t      (1)

d=total distance.
s=speed.
t=time spent by Miranda for she overtook her father.

Distance traveled by Miranda.
data:

s=48 miles/ hour
d=total distance.
t=time spent by Miranda for she overtook her father.

d=48 miles/hour * t      ⇒d=48t       (2)

With the equations (1) and (2), we make an system of equations:

d=80+40t
d=48t

We can solve this system of equation by equalization method.

80+40t=48t
80=48t-40t
80=8t
t=80/8=10

d=48t
d=48*10=480

Answer: the thistance will be 480 miles.

The stock of Company A lost 2% today to $46.55. What was the opening price of the stock in the beginning of the day?
cluponka [151]

Answer:

$2327.5

Step-by-step explanation:

The stock of company A lost 2% today .

Let the price of the stock at the beginning of the day be A.

Therefore, a 2% loss of A = $46.55

That’s

2% /100% x A = $46.55

0.02 x A = $46.55

Divide both sides by 0.02

0.02/0.02 x A = $46.55/0.02

A = $2327.5

The price of stock at the beginning of the opening day was $2327.5
