She runs at a constant speed, and she bicycles at a speed of 777 meters per second (\text{m/s})(m/s)left parenthesis, start text, m, slash, s, end text, right parenthesis. Let RRR represent the number of seconds that Guliskhan runs and BBB represent the number of seconds that she bicycles according to her plan. 3R+7B \geq 10003R+7B≥10003, R, plus, 7, B, is greater than or equal to, 1000 According to the inequality, at what speed does Guliskhan run, and what is the minimum distance that she plans to cover? Guliskhan runs at a speed of \text{m/s}m/sstart text, m, slash, s, end text, and plans to cover a minimum distance of meters. Can Guliskhan cover this minimum distance if she runs for 606060 seconds and bicycles for 909090 seconds?
