lia each take a bicycle trip. Anna rides 20 km 1 1/3 hours. Julia rides 100 meters in 10 minutes. Which rider has the slower unit rate?
Anna:
20 km / 1 1/3 hr
= 20000 m/80 min
= 250 m/minute
Julia:
100 m/10 min
= 10 m/minute ????? I suspect a typo somewhere
its julia i found out
To determine which rider has the slower unit rate, we need to compare their rates of distance traveled per unit of time.
First, let's calculate the unit rate for Anna. Anna rides 20 kilometers in 1 1/3 hours. To find the unit rate, we need to divide the distance by the time. 1 1/3 hours can be converted to an improper fraction as (4/3) hours. Therefore, Anna's unit rate can be calculated as:
Unit rate for Anna = Distance / Time
= 20 km / (4/3) hr
= 20 km * (3/4) hr (multiplying by the reciprocal)
= 15 km/hr
So, Anna's unit rate is 15 kilometers per hour.
Now let's calculate the unit rate for Julia. Julia rides 100 meters in 10 minutes. We need to convert the time to hours since Anna's unit rate is also in hours. To do this, we divide the time by 60 (as there are 60 minutes in an hour). Therefore, Julia's unit rate can be calculated as:
Unit rate for Julia = Distance / Time
= 100 m / (10/60) hr
= 100 m * (60/10) hr (multiplying by the reciprocal)
= 600 m/hr
So, Julia's unit rate is 600 meters per hour.
Comparing the unit rates, we can see that Anna's unit rate is 15 km/hr, while Julia's unit rate is 600 m/hr. Since 600 m/hr is a smaller unit compared to 15 km/hr, it means that Julia has the slower unit rate.
Therefore, Julia has the slower unit rate.
