What does rounding to the nearest ten square feet mean?

Answers

Round to the nearest tens place.

Final answer:

Rounding to the nearest ten square feet means finding the closest multiple of ten to a given area in square feet.

Explanation:

Rounding to the nearest ten square feet means finding the closest multiple of ten to a given area in square feet. This is done by looking at the tens digit of the number. If the tens digit is 5 or greater, you round up to the next multiple of ten. If the tens digit is less than 5, you round down to the previous multiple of ten. For example, if you have an area of 67 square feet, rounding to the nearest ten square feet would give you 70 square feet.

1. You live in Raleigh and plan to fly to Ottawa, Canada where the fishing is really good. It is 1,345 km. You book a non-stop flight for the two of you. If the jet flies 450 miles per hour, how long is your flight?

Answers

It takes 2 hours for the flight to reach Canada

Solution:

Given that You live in Raleigh and plan to fly to Ottawa, Canada

Distance is 1345 km

The jet flies 450 miles per hour

To find: Time taken to reach Canada

The time taken is given by formula:

$Time = (distance)/(speed)$

From given,

Distance = 1345 km

Convert to miles

1 km = 0.621371 miles

Therefore,

1345 km = 835.7443 miles

Substituting in formula, we get,

$Time = (835.7443)/(450)\n\nTime = 1.8572 \approx 2$

Thus it takes 2 hours for the flight to reach Canada
