Ответ:
Step 2. Given, 1 hour = 60 minutes then 45 minutes* 1 hour/60 minutes = 0.75 hour
Step 3. Speed or average rate = 3 miles/(0.75 hour)=12/3 mph= 4 mph
Step 4. ANSWER: The average rate is 4 miles per hour.
Ответ:
Lauren ran for 45 minutes.
We first calculate what percentage/fraction 45 minutes is of 60 minutes:
45/60 = 3/4
45 minutes is 3/4 of one hour
We also know she traveled 3 miles in only 45 minutes. Now we have to calculate how much she would travel in the remaining 15 minutes.
What we simply do is calculate the speed = distance/time:
The 3 miles / (3/4) h = 4 miles
This then tells us tthat she would travel 4 miles per hour.
Ответ:
What's the exponents?
Step-by-step explanation:
5.2+3.01=8.21
but then there's no exponents that you stated. So it would be 8.21x10^?
If the tens do have exponents above them, add them together.
I hope this answer helps you!
