It will take 3 hours 6 minutes 40 seconds for the cars to be 420 miles apart.
Step-by-step explanation:
Step 1; The cars are traveling in the opposite direction at different speeds. One is going north at a speed of 75 mph while the other is going 60 mph. So for every hour, the cars are traveling they increase the distance between in between themselves by 75 miles + 60 miles = 135 miles.
Step 2; Assume that in x hours the distance between them is 420 miles. To calculate x we divide the distance to be traveled by the distance being traveled every hour.
x = distance to be covered / distance being traveled every hour
= 420 / 135 = 3.11 hours
We multiply the 0.11 hours with 60 to convert it into minutes. 0.11 × 60 = 6.66 minutes and if we do the same for seconds, 0.66 minutes × 60 = 40 seconds.

Step-by-step explanation:
Answer:
perimeter of rectangle=2(l+b)
=2(13.5+7)
=2*20.5
=41
area of rectangle=l*b
=13.5*7
=94.5 inch^2
area of triangle=1/2*b*h
=9.48*4.2/2
=19.90
=19.9
perimeter of triangle=a+b+c
=(4.46+9.48+10) inches
=23.94 inches^2
to find x
7x+2=3x+18
7x-3x=18-2
4x=16
x=16/4
x=4
perimeter of rectangle=2(l+b)
=2(7x+2+12.5)
=2(7*4+12.5)
2*40.5
=81
perimeter of triangle=1/2*b*h
=7.3*6.3/2
=45.99/2
=22.99
=23 mm^2
area of a triangle=a+b+c
=s+s+s
=7.3+7.3+7.3
=21.9 mm^2
Radius=14 inc
diameter=radius*2=28 inc
circumference=2πr
=2*3.14*14
=87.92
area of ciecle=π
=3.14*(14)^2
=3.14*196
=615.44
Step-by-step explanation:
1 1/2 hours on the treadmill. 1/2 hour outside. 9 miles on the treadmill. 1 mile outside.
Answer:
Let pork chops and ground beef be x and y respectively.
4x = $12.60
x = $3.15
11x = $34.65
5y = $10.25
y = $2.05
12y = $24.60
11x + 12y = $34.65 + $24.60
= $59.25
