Step-by-step explanation:
First step:
Distance = 300km
Speed = 60km/hr
We know,
Using Speed = Distance ÷ Time
Time = Distance ÷ Speed
we have Total Time = 300÷60
Total Time = 5hr
Again,
Distance = 200km. (Time = 5hr,
Speed =? Distance = 200)
Speed = Distance÷ Time
= 200÷5
= 40km/hr

Slope = 
Step-by-step explanation:
Slope = 
Slope = 
Slope = 
Slope = 
Slope =
You multiply top and bottom of the fraction by the conjugate of 5 - √2 which is 5 + √2. This produces a rational denominator:-
= √7 ( 5 + √2) / (5 - √2)(5 + √2)
= √7 ( 5 + √2) / (25 -2)
= (√7 ( 5 + √2)) / 23 answer
