<span><span>A cargo plane flew to Moscow and back. It took six hours longer to go there than it did to come back. The average speed on the trip there was 152 mph. The </span></span><span>average speed on the way back was 380 mph. How many hours did the trip there take? (x + 6)152 = 380x 228x = 912 x = 4 The trip there took 10 hours.</span>
Given: Choose a number between 0 and 20. If the difference is less than 10 then Eric wins. Let us x is Eric's number. 0 <u><</u> x <u><</u> 20 If Eric wins. |x -7| < 10 |x-7| < 10 → -10 < x-7 < 10 → -10 + 7 < x - 7 + 7 < 10 + 7 → -3 < x < 17
Taking into account that the number must be given between 0 and 20. 0 <u><</u> x <u><</u> 20 -3 < x < 17
