Roger ran for 1 hour 15 minutes at an average speed of 12 km/h. How many meters did he run?
he ran 1.25 * 12 km
Now convert that to meters.
why 1.25?
because 15 minutes is 1/4 = .25 hour. So, 1 hr 15 min = 1.25 hours
distance = time * speed, as calculated.
thanks

yes 12+3 = 15 :)
To find out how many meters Roger ran, we need to calculate the distance traveled based on his average speed and the time he ran.
First, we need to convert the time from 1 hour 15 minutes to decimal hours. There are 60 minutes in an hour, so we can write 1 hour 15 minutes as 1.25 hours. This is because 15 minutes is equal to 15/60 = 0.25 hours (15 divided by 60).
Next, we can use the formula: distance = speed × time
Roger's average speed is 12 km/h, and he ran for 1.25 hours. Plugging these values into the formula, the calculation is:
distance = 12 km/h × 1.25 hours
Now we multiply 12 by 1.25: 12 × 1.25 = 15
So, Roger ran a distance of 15 kilometers.
To find out how many meters he ran, we need to convert kilometers to meters.
1 kilometer is equal to 1000 meters. Multiplying 15 kilometers by 1000, we get:
distance in meters = 15 km × 1000 = 15,000 meters
Therefore, Roger ran 15,000 meters.
