Acar travels at constant speed for 7 days and covers 1500 miles. what is the speed in centimeters/minute? you may use the (approximate) conversion factors on page 55 of the text (in particular that 1 mile is about 8/5 km), or you may relate everything to the conversion 1 inch = 2.54cm.

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

Distance traveled = 1500 miles and time taken = 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

Therefore, speed = 23809.52 cm/min

the answer to the expression is 83
