Question

PLEASE HELP ME ,THIS IS HARD ,AND I DON’T UNDERSTAND MATH..

Answer 1

Explanation:

divide y by x

in a table and coordinate pair, which is something like (0,4), x always comes first. So, in this table x is the time in seconds and y is the distance in meters. 120/4=30 meters per second. For the second part of the table, since we know what the slope is, or the constant rate of change, 30, we can multiply 30 by 25 which is 750. You can also use the equation y=mx, m is the slope, and x is a point on the coordinate pair. For example, in the second table, y=30(25). For the last part of the table, you can use the same equation. 270=30x. We try to get x alone so we do, 270 divided by 30 which is 9. So a cheetah runs at 270 meters per 9 seconds.

Answer 2

The answer above me is totally correct and has a very good explaination
But I’m still doing this
In the first part it is given time = 4s
Distance = 120m
And we have to calculate it’s speed
We know that speed = Distance/Time
So speed = 120/4
So speed = 30m/s
In second question
Now in the question it is given that cheetah walks at a constant speed
So here time= 25 seconds
Speed= 30m/s (from 1st question)
So distance= speed*time
distance = 30*25
Distance = 750m
Now in third question
Distance is given 270m
Also we know speed = 30m/s
So time = Distance/speed
Time= 270/30
Time = 9 seconds
So answers are
1st part - speed = 30m
2nd part - Distance = 750m
3rd part - Time = 9s
Hope it helps you!
That was a long question btw
