Final answer:
To find the speed in meters per hour, divide the distance by the time and convert the time from minutes to hours.
Step-by-step explanation:
To find the speed in meters per hour, we need to convert the time from minutes to hours. Since there are 60 minutes in an hour, we divide the time by 60: 15 minutes ÷ 60 = 0.25 hours. Now, we can calculate the speed by dividing the distance by the time: 150 meters ÷ 0.25 hours = 600 meters per hour.
