Step-by-step explanation:
12 1/2 - 8 5/6
25/2 - 53/6
(75-53)/6
22/6
11/3
3 2/3
It’s D , -16.2
you replace X with -142 and get -0.2 (142 + 223)
U can. Do 3+4 u just switch the number
Answer:
73
Step-by-step explanation:
584/8
To solve the problem we will use this equation where,
d will be distance.
x is the speed of the plane without tailwind.
y is the speed of the wind affecting the plane.
Going to Philadelphia the speed of the plane affected by wind will be x-y=220 miles/hr
Coming back with a tailwind, the speed of the plane will be x+y= 280 miles/hr.
since time = distance / speed, t1 =d/220 and t2 = d/280
and since the total time traveled is 6.5hrs
d/220 + d/ 280 = 6.5hrs
d = 800.8 miles x 2 (back and forth trip) the answer is 1601.6 miles
