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
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.
