If Sasha can run 720 yards in 4 minutes, how many feet can she run in 15 seconds?

1 answer:

6 0

Okay so you're trying to find the unit rate of 720yds/4min. If you divide 720 by 4 you will have the unit rate as 180yds/1 min or 60 sec then if you divide 180 and 60 by 4 again you will get the answer of 45yds/15sec.

Answer:

440cm³

Step-by-step explanation:

Area of trapezium base=

$\frac{1}{2} \times (a + b) \times h$

$\frac{1}{2} \times (8 + 14) \times 4$

$\frac{1}{2} \times 22 \times 4 \\ = \frac{88}{2} \\ = 44 {cm}^{3}$

Volume=Area or trapezium x Height between trapezium ends

$= 44 \times 10 \\ = 440 {cm}^{3}$
