How to multiply to the n<br>earest ten
Tcecarenko [31]
I'm not sure what you mean by this, but if you mean rounding, I got an answer.

Say you're rounding 24 to 30.
24 is closer to 20 than 30.

But if you were rounding 25 to 30, 25 would be closer to 30, not 20.
I guess it's kind of confusing.

To get on a certain toll road a driver has to take a card that lists the mile entrance point. The card also has a timestamp. Whe
kolezko [41]

Answer:

Step-by-step explanation:

This can happen because of the timestamp on the toll card. When you pass through the initial entrance point the timestamp marks the exact moment you passed. When you pass through the exit toll point the individual subtracts the current time from the time you entered the initial toll entrance. From this, he can easily determine the average speed that you were driving at. If the average speed is higher than the speed limit, it means that at some point between the two toll booths you were speeding and therefore they can give you a speeding ticket.

it took Simon 33 minutes to run 5.5 miles. did he run faster or slower than 1 mile every 5 minutes how can you tell ​
vitfil [10]
Simon ran slower than 1 mile every 5 minutes.

Because 33 / 5.5 = 6. So he ran 1 mile every 6 minutes, not 5.
