Answer:

120*2.75*60/5280

= 3.75

Step-by-step explanation:

Considering James takes 120 steps in a minute, with 60 minutes in an hour and a mile consisting of 5,280 feet, we can establish his walking pace. By multiplying his steps per minute by the distance of each step (120 * 2.75), we determine the distance he covers in one minute. This value is then multiplied by 60 to account for the total hour. Finally, the total distance is divided by the feet in a mile (5,280), which results in a speed of 3.75 miles per hour. Thus, the calculation becomes 120*2.75*60/5280

x = lowest height

<x+25 highest height

x=55

Respuesta: 4,000

Explicación paso a paso: para este caso estamos viendo cuántas veces encaja 0.02 en 80. 0.02 * 50 = 1, así que luego multiplicamos 50 * 80 y obtenemos nuestra respuesta de 4,000. Espero que esto sea útil
