Sarah runs 3 miles in 25 minutes, at the same rate how many miles would she run in 2o minutes?
4/5 the time, so 4/5 the distance -- 4/5 * 3 = ____ miles
rate trial=rate total run
or 3mi/25min=xx /20min
xx=60/25 miles=2 2/5 miles
To find out how many miles Sarah would run in 20 minutes at the same rate, we can use the concept of speed or rate. The formula for speed is distance divided by time. In this case, the distance is given (3 miles) and the time is given (25 minutes).
To find Sarah's rate, we can divide the distance by the time: rate = distance / time. In this case, the rate = 3 miles / 25 minutes.
To find out how many miles Sarah would run in 20 minutes at the same rate, we can use the formula: distance = rate * time. In this case, the rate is 3 miles / 25 minutes, and the time is 20 minutes.
Let's calculate it:
distance = (3 miles / 25 minutes) * 20 minutes
First, we divide 3 miles by 25 minutes to find our rate:
rate = 3 miles / 25 minutes = 0.12 miles/minute
Then we multiply the rate by 20 minutes to find the distance:
distance = 0.12 miles/minute * 20 minutes = 2.4 miles
Therefore, Sarah would run approximately 2.4 miles in 20 minutes at the same rate.
