Answer:
The speed of car in miles per minute is miles per minute and
The speed of car in mile per hour is 40 miles per hour,
Step-by-step explanation:
Given as :
The distance cover by car = 2 =
miles
The Time taken by car to cover distance = 3 min =
min
The speed o car in miles per minute = S miles/min
So, Speed =
Or, S = mie per min
∴ S = miles per minute
Now, Let The speed of car in miles per hour = x miles/h
So, Time in hour = ×
=
hours
So , Speed =
Or, x = miles per hours
Or, x = 40 miles per hours
Hence The speed of car in miles per minute is miles per minute and the speed of car in mile per hour is 40 miles per hour, answer
Answer:
∠GJK is 22°
Step-by-step explanation:
Because the shape is a rectangle we know that GH is parallel to JI
This means that because of the alternate angle rule we know that
5x+8 = 7x-16
Then we solve for x
5x+8-5x = 7x-16-5x
8+16=2x-16+16
=
x=16
So this means that ∠HJI is 68°
Because the shape is a rectangle we know that ∠GJI is a right angle
This means that ∠GJK is 90-∠HJI because of the angles on a right angle rule
90-68 =22
∴∠GJK is 22°
