K, you have 2 minutes, one minute for one kilometer.
If you're in 60km/h, you're on 1km/m, so, if you cover 1 km in one minute, you need to stay in that speed to get to the train station.
<span>In this question you need to find the lowest common multiple. I like to
do it the factor tree way:<span>
<span>
15
9</span>
/ \
/ \
3 5
3 3
See how there are both a 3 in the 15 factor tree
and there is at least on three in the 9 factor tree. So when you find the LCM,
you combine the two threes from the different factor trees like this:
3 x 5 x 3 = 45
So every 45 minutes the bus would be at the bus
stop together
Now simply add the 45mins onto the 1:25
<span>Answer: 2:10 </span></span></span>
He should set up the refreshment stand on the incenter of the obtuse triangle. The incenter of a triangle is described as the intersection between the angle bisectors of a triangle. The inradius are the line segments from the incenter of the triangle to each of the three sides of the triangle which are all equal. The inradius is depicted as the radius of an inscribed circle in the triangle. Therefore, the shortest equal distance from his stand to each road is C. on the incenter.
Fist you need to substitute the value of R into the equation
25-6(3)
Now you simply
First multiple 6(3)
25-6(3)
25-18
Now solve!
25-18
7
The answer is 7
