Ben also participated. He fell down midway, and had to walk part of the distance. Still, he finished the distance! It took him e

sammy [17]

Answer:

0.56 m/s

Step-by-step explanation:

The average speed of a body tells how fast is the body moving; it is calculated as:

$v=\frac{d}{t}$

where

d is the distance covered

t is the time elapsed

In this problem, we don't know the distance covered by Ben. Therefore, we will assume that it is 1 km:

d = 1 km = 1000 m

The time elapsed to cover this distance is:

$t=30 min \cdot 60 =1800 s$

Therefore, Ben's average speed is:

$v=\frac{1000}{1800}=0.56 m/s$

PLEASE HELP? SERIOUSLY? :)

IRINA_888 [86]

2x + 5y = -8 . . . (1)
-133x - 4y = -8 . . . (2)

(1) * 4 => 8x + 20y = -32 . . . (3)
(2) * -5 => -665x + 20y = 32 . . . (4)

(3) - (4) => 673x = 0
x = 0
From (1), 2(0) + 5y = -8
5y = -8
y = -8/5
