The speed of Washington Plane is 500 mph and LA plane is 600 mph.

Step-by-step explanation:

Given :

The distance between the cities is 2700 miles.

Solution :

Let v and u are the speeds of the two planes of Washington and LA respectively.

Given that after two hours the distance between them was still 500 miles, therefore

$\rm 2v +2 u + 500 = 2700$ ---- (1)

It is also given that LA plane was 100 mph faster, so

$\rm u = 100 +v$ ---- (2)

Now put the value of u in equation (1) we get,

$\rm 2v +2(100+ v ) +500 = 2700$

$\rm 4v = 2000$

v = 500 mph

Now put the value of v in equation (2),

u = 600 mph

Speed of the plane from Washington: $500\ mph$

Speed of the plane from LA: $600\ mph$

Step-by-step explanation:

We need to remember that:

d=Vt

Where "d" is distance, "V" is speed and "t" is time.

Let be "w" the speed in mph of the plane from Washington and "l" the speed in mph of the plane from LA.

We know that the distance between the cities is 2700 miles and after they flied for 2 hours, the distance between them was 500 miles. Then we can write the following equation:

2w + 2l + 500 = 2700 [Equation 1]

Since the speed of the plan from LA was 100 mph faster, we can write this equation:

l=w+100 [Equation 2]

The steps to solve this are:

1. Substitute the Equation 2 into the Equation 1 and solve for "w":

$2w + 2(w+100) + 500 = 2700\\\\4w+200+500=2700\\\\w=\frac{2000}{4}\\\\w=500$

2. Substitute the value of "w" into the Equation 2 in order to find "l":

$l=500+100\\\\l=600$

step-by-step explanation:

to find the amount of gift bags to use all the supplies, find the gcf or greatest common factor. this is the largest number which multiplies evenly into each term.

48 has factors: 1, 2, 3, 4, 6, 8, 12. 16, 24, 48

80 has factors: 1, 2, 4, 5, 8, 10, 16, 20, 40, 80

64 has factors: 1, 2, 4, 8, 8, 16, 32, 64

the highest number factor they all share in common is 8. this means there will be 8 bags with 6 pencils, 10 markers, and 8 stickers in each bag.
