The answer is: " 16 " .
____________________________
Explanation:
____________________________
Method 1)
____________________________
(4/5) *(20/1) = ?

The "5" cancels to a "1" ; and the "20" cancels to a "4" ;
(since "20÷5=4" ; and "5÷5=1") ;
________________________________
Rewrite as: (4/1) * (4/1) = 4 * 4 = 16.
_________________________________
Method 2)
_______________________________
4/5 * 20/1 = (4*20)/(5*1) = (80/5) = 16 .
_________________________________
Method 3)
_________________________________
4/5 * 20 = ? ;

4/5 = 8/10 = 0.8 ;

0.8 * 20 = 16.0 = 16.

Andre runs for 35 seconds at a velocity of -8 meters per second. He is running west. What is his finishing position?

user100 [1]

Answer:

d = -280 m

Step-by-step explanation:

Given that,

Velocity of Andre, v = -8 m/s

Time taken, t = 35 seconds

We need to find his finishing position. Let the finishing position be x.

We know that,

Velocity = distance/time

So,

$d=v\times t\\\\d=-8\times 35\\\\=-280\ m$

so, he was at a distance of 280 m in west.
