try this
Step-by-step explanation:
19 g
Use the quadratic formula .
x^2-2x+11=0
a=1
b=-2
c=11
x=-2+- (-2)^2-4*1*11 divided by 2
x=2+- the square root of -40 divided by 2
There is no real solutions
The distance between them is 252 miles
For meeting they reduce the distance with 252 miles
in an hour they reduce distance with 100+80=180 miles
180 miles...........1 hour
252 miles.............x hours
------------------------------------
x=252 /180=1,4 hours=84 minutes
