Cheetah ran 300 feet in 2.92 seconds.
Average speed in miles per hour.
Converting 300 feet to mile.
5280 feet = 1 mile
1 feet = (1/5280) mile
300 feet = (1/5280) * 300 = (300/5280) = (30/528) = (10/176) mile.
2.92 seconds to hour.
3600 seconds = 1 hour
1 second = (1/3600) hour
2.92 seconds = 2.92 * (1/3600) = (2.92/3600) hour.
Speed of Cheetah in miles per hour = (10/176) mile / (2.92/3600) hour
= 70.05 miles/hour

Answer:
$39
Step-by-step explanation:
First, let's get the values of each number by <u>rounding them off to the nearest dollar before adding them</u>.
- Remember that you have to <em>round off the number up</em> if it is being followed by a number<em> </em><u><em>equivalent to 5 and above.</em></u><em> </em>You have to <em>retain the number</em> if it is followed by a<u><em> number less than 5</em></u>.
1. $2.69 = $3
2. $14.45 = $14
3. $8.05 = $8
4. $13.95 = $14
Now that you have the rounded off numbers, you may add them.
Let's solve.
- $3 + $14 + $8 + $14 = $39
The estimated total is $39.
