The passenger train takes (D/96) hours to cover the distance 'D'. The freight train takes (D/64) hours to cover the same distance 'D'. You've told us that (D/96) is two hours less than (D/64). OK. D/96 = D/64 - 2 Multiply both sides by 16: D/6 = D/4 - 32 Subtract (D/4) from each side: D (1/6 - 1/4) = -32 D (2/12 - 3/12) = -32 D (-1/12) = -32 Multiply each side by -12: D = 384 Km. Caution. The trip from Norman to Enid is fraught with danger. Afternoon rush-hour through Yukon is no picnic. But if you try and avoid it by taking the east route around OKC, then you've got to stop at the Wagon Wheel Barbecue in Shawnee, which totally blows your schedule.
That 8 might equal D. Trashed. "Eight Equals D" is: 8=D Which is a penis smiley -.- ~ Skullcandy88
you write it as 75 and the answer is 16,807 :D
(It's a penis) 8=====D 8 = balls D = head
U1 = a = 12 U2 = a + 1*d = 12 - 2 = 10 U3 = a + 2*d = 12 - 4 = 8 U4 = a + 3*d = 12 - 6 = 6 U5 = a + 4*d = 12 - 8 = 4
15+d^2=96 d^2=96-15=81 so d=9 or d = -9
d = 11
4
Area of a circle = pi*r*r or pi*d*d/4 where r is the radius, d the diameter. Area = pi*96*96/4 = 7238.23 sq inches.
And what is the question?
The passenger train takes (D/96) hours to cover the distance 'D'. The freight train takes (D/64) hours to cover the same distance 'D'. You've told us that (D/96) is two hours less than (D/64). OK.

4 wheel drive
D/4 = 1.7 Multiply both sides by 4 to find the value of D:- D = 6.8
d = 60 miles r = 15 mi/hr t = ? d = rt and t = d/r t = 60 mi/15 mi/hr = 4 hr Since, traveling is going and coming back, then the time is 8 hours.
If its 2a=8 then a= 4 If a=8 then a2=16 If 8=D then 8=====================================D
Divide both sides by 4: c = d/4
equals D repeater
