Susie left her house and drove at 40 km/h for 6 hours to reach Carlos's house.
She took the same route back at 60 km/h. How far did Susie drive one way?
How long did it take her to get home?

240 kilometers - to reach Carlos's house

4 hours - to get back home

Step-by-step explanation:

1). 40 km/h * 6 h = 240 km - distance to Carlos's house

2). 240 km / 60 km/h = 4 h - it took her to get back home

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.  

the reporter's right
