Twelve boys collected 16 aluminum cans each. fifteen girls collected 14 aluminum cans each. how many more cans did the girls collect than the boys

First multiply 12 by 16 to find the total number of cans the boys collected.

12 * 16 = 192

Do the same thing with the girls.

15 * 14 = 210

Now, subtract the 2 amounts.

210 - 192 = 18

The girls collected 18 more cans than the boys.

Hope this helps!

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
