Elena went 60 meters in 15 seconds Noah went 50 meters in 10 seconds Elena and Noah both moved at a constant speed .how far did
2 answers:
Answer:
4 meters
Step-by-step explanation:
About Elena we know that she moves at 60 meters each 15 seconds:
Distance Time
60m → 15s
and we want to know how far she would go in only 1 second:
Distance Time
60m → 15s
x → 1s
where x is the unknown distance, that we calculate as follows: multiply the cross quantities in the table and divide by the other number in the corner.
In one second she will travel 4 meters.

Answer:
<em>B. 138,000 square yards </em>
Step-by-step explanation:
The figure can be divided into two shapes (see attachment 2)
From attachment 2,
The dimension of the big rectangle is 1300ft by 800ft
The dimension of the small rectangle is 500ft by 400ft
So, the area is:
Area of the big rectangle added to the area of the small rectangle
i.e.
Convert to by dividing by 9
