Answer:
12 minutes
Option D
Step-by-step explanation:
Given that circuar gears P and Q start rotating at the same time at constant speeds.
Gear P makes 10 revolutions per minute and Gear Q makes 40 revolutions per minute.
Both gears start at the same time.
No of rotations per minute are 10 and 40
Difference is 30 in one minute
For 6 difference we must have exactly 1/5 minutes
which equals 12 seconds.
In 1/5 minutes or 12 seconds gear P would have completed 2 revolutions while Gear Q would have completed 8 revolutions thus making difference as 6.
Answer:
3+5-2x4x1
3+5=8
2x4=8x1=8
8-8=0
Step-by-step explanation:
To solve this I offer you to download All in one calculator.
if you give the sides or a side and an angle
or a side and hypotenuse, this app will give you the unknown parts of the triangle.
a side is 500m and an angle is 80 (90-10=80)
x will be 2879.39
hope this helps
