Final answer:
To find how long it takes to jog 1.2 miles at a rate of 9 mph, we first convert the speed to miles per minute (0.15 miles/min) and then divide the distance by the speed, resulting in 8 minutes.
Step-by-step explanation:
To calculate the time it takes for an endurance athlete to jog 1.2 miles at a rate of 9 miles per hour, we can use the formula: time = distance ÷ speed. First, we need to convert the speed to miles per minute because we want the time in minutes. Since there are 60 minutes in an hour, 9 miles per hour is the same as 9 ÷ 60 = 0.15 miles per minute.
Next, we use the formula to find the time: time = 1.2 miles ÷ 0.15 miles per minute = 8 minutes. Therefore, it takes the athlete 8 minutes to jog 1.2 miles.
