How far will a train travel in 5 hours if it travels at 80 miles per hour?

Answer:

  C.  400 miles

Step-by-step explanation:

In each hour, it travels 80 miles. (That is the meaning of "80 miles per hour.") So you can add up the distances over a period of 5 hours:

  80 miles + 80 miles + 80 miles + 80 miles + 80 miles

After the first sum (80+80=160), you can see what the correct answer will be. Continuing, you find the sum to be ...

  = 400 miles

___

Multiplication was invented to make repeated addition easier.

  5 × 80 miles = 400 miles

_____

Strictly speaking, you are multiplying numbers with units here:

  (5 h) × (80 mi/h) = 400 mi·h/h = 400 mi . . . . . . the units h/h cancel

andrew-mc [135]

Answer:

Step-by-step explanation:

(find the percent by multiplying the percentage, .45, by the total number of shoes = 18 shoes)

% = 45%

p = 18

w = 40

(i did 100/40 which equals to 2.5 then multiplied 2.5 by the numerator so the numerator and denominator would both be equivelant.)

18/40 = 45/100

(multiply the whole (40) by the decimal value (.45) which is equal to 18)

40 x .45 = 18

(answer)

If Ms. M has 40 pairs of shoes, 18 of those shoes are sneakers.
