The speed limit on a highway is 55 mph. a speed sensor showed that a car went 900 ft in 8 s. is the car traveling over the speed limit? explain.

900 feet / 5,280 = 0.1704545... miles

8 seconds / 3,600 = 0.0022222222 hours

0.1704545 miles / 0.0022222222 hours = 76.704525767 miles per hour

The car is well over the speed limit

Step-by-step explanation:

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.
