You and your friend meet at your house and ride bikes in opposite directions. You travel at 12 miles per hour and your friend is traveling two miles per hour faster. How far apart will you be after 3 hours?

42

Step-by-step explanation:

you're traveling 12 miles every hour.

12 * 3 = 36

in 3 hours you will have traveled 36 miles.

your friend is traveling 2 miles every hour.

2 * 3 = 6

In 3 hours they will have traveled 6 miles

The distance between you is the miles you traveled + the miles they traveled.

36 + 6 = 42

You will be 42 miles apart after 3 hours

add all the numbers and check the ones place.

the answer is 486. as the ones place is more than 4, the estimation will be the next 10 ie, 490

false

step-by-step explanation:

false.   two legs of the trapezoid would be congruent, but the other two would not.   were all the legs congruent, then we'd have a square; were the 2 shorter sides congruent and the 2 longer sides also congruent, we'd have a rectangle.
