Answer:

The cross product property

Step-by-step explanation:

The cross product property also known as cross multiplication is a method in math that is most of the time used in solving problems involving ratios usually in a big X form across the equal sign between two ratios.

It is done by multiplying the numerator of the left ratio by the denominator of the right with an equal to the multiplication of the numerator of the right ratio by the denominator of the left.

Answer:

Speed = 23809.52 cm/min      

Step-by-step explanation:

Given : A car travels at constant speed for 7 days and covers 1500 miles.

To find : What is the speed in centimeters/minute

Solution : Formula to find speed is

\text{Speed}=\frac{\text{Distance}}{\text{Time}}

Distance traveled = 1500 miles and time taken = 7 days

\text{Speed}=\frac{\text{1500 miles}}{\text{7 days}}

Now, we have to convert miles into centimeter and days into minutes.

1 day = 24 hours

1 hour= 60 minute

24 hr= 24×60 minute

1 day =  24×60 minute

7 days = 7×24×60 minute = 10,080 minute

Now, 1 mile = 8/5 km = 1.6 km

1 km= 100000 cm

1.6 km = 1.6 × 100000 cm

1 mile = 1.6 × 100000 cm

1500 miles = 1500×1.6 × 100000 cm = 240,000,000 cm

Put back the values into speed

\text{Speed}=\frac{\text{1500 miles}}{\text{7 days}}

\text{Speed}=\frac{\text{240,000,000 cm}}{\text{10,080 minute}}

\text{Speed}=\text{23809.523 cm/minute}

Therefore, speed = 23809.52 cm/min
