Question: The Mach number M of a moving object is the ratio of its velocity v to the velocity of sound v s , and v

The Mach number M of a moving object is the ratio of its velocity v to the velocity of sound v_s, and v_s varies with temperature. A jet traveling at 1650 km/h changes its altitude from 500 m to 5500 m. At 500 m (with the temperature at 27° C), v_s = 1250 km/h, and at 5500 m (−3°C), v_s = 1180 km h. Express the range of M, using an inequality with absolute values.
