Answer:
Step-by-step explanation:
For plane A,
Equation that represents the relationship between time 'x' and distance 'y' is,
y = 470x
By comparing this equation with the slope-intercept form of the equation,
y = mx + b
m = slope = 470
b = 0
Here, slope represents the speed of plane A.
Therefore, speed of plane A = 470 mi per hour
For plane B,
From the given table,
Slope of the graph = 
= 
= 480
Speed of plane B = 480 miles per hour
Since, speed of plane B is more than plane A,
Plane B is flying faster.

Answer:
The total distance cover by John is 15 min to reach his office .
Step-by-step explanation:
Given as ;
In the first 10 minutes , the distance cover is 1 miles every minutes
So, for 10 minutes , total distance cover by John = 10 × 1 = 10 miles
Again ,
John cover distance of 0.5 miles for every minutes , he travel for next 10 min
So, for next 10 min, total distance cover by John = 10 × 0.5 = 5 miles
So, The total distance cover by john = 10 miles + 5 miles = 15 miles
Hence The total distance cover by John is 15 min to reach his office . Answer
