Answer:
30 mph
Step-by-step explanation:
First we need to find the distance travelled in the first 1h30m.
We can do that multiplying the speed by the time travelled, so we have:
Distance1 = 50 * 1.5 = 75 miles
If the total distance is 120 miles, Michael still needs to travel 120 - 75 = 45 miles.
And if the total time travelled is 3 hours (10 AM - 7 AM), the second part of the travel has a duration of 3h - 1.5h = 1.5h
So if the distance is 45 miles and the time is 1.5 hours, we can find the speed of the second part:
45 = speed * 1.5
speed = 45/1.5 = 30 mph
You take 187 away from 2431

SU and RT both intersect the circle at 2 points and are secants
Answer:
14 and 6
Step-by-step explanation:
Let's start by naming the first number x.
We can name the second number y.
We can set up equations to model our situation.
x+y=2x-8
x-y=2y-4
Let's simplify the equations.
x+y=2x-8
Subtract 2x from both sides
-x+y=-8
__________
x-y=2y-4
Subtract 2y from both sides.
x-3y=-4
Add the two equations together to eliminate x.
x-3y=-4
-x+y=-8
________
0x-2y=-12
-2y=-12
Divide both sides by -2.
y=6
The second number is 6.
Plug that back in.
x+6=2x-8
Subtract x from both sides
6=x-8
Add 8 to both sides
x=14
The first number is 14
