A passenger train takes 2 hours less than a freight train takes to travel from Norman to Enid The passenger train averages 96 km hr while the freight train averages 64 km hr What is the distance fr?
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.

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
