You’re going to use the formula: y2-y1/x2-x1
plug that in: 0 - 3/-1 - 2 = -3/-3 or 1
Answer:
zero im pretty sure
Step-by-step explanation:
Answer:
It will take 4.5hrs to cover the same distance
The constant of variation,k=252
Step by step explanation
Given that,

From the question
Time=4hr
Speed=63km
By substitution we obtain,

Cross multiplying we get,


Now,
speed=56km
Distance Covered=252km
By substitution:
We obtain,

Cross multiply

Divide through by 56


From the formula,

Which means that, speed and time varies inversely.

Let k be variation constant
This implies that


Taken,
Time=4hrs
speed=56km


Answer:
Chloe swam further. 16/40 to 25/40
Step-by-step explanation:
2/5 5/8
Find greatest common factor of 5 and 8 which is 40.
5x8=40 so multiply the same at the top.
2/5=16/40
5/8=25/40
16/40<25/40.
