It’s 5 to 10 seconds EXPLANATION: if you were to go from 49 feet in the air to 19 feet in the air, which means you descended, You would’ve gone -30 feet in 5 seconds. This means that for you to go from 19 to 20 feet in 5 seconds, you would’ve gone through the least change.

10. Mr. Guerrero left his house and drove north at an average speed of 40 mph.Two hours later, his daughter Miranda left the hou

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.
