Answer:
90min
Step-by-step explanation:
we can solve the first part by means of the rule of three:
5.3miles ----2.5 hour
3.18miles----x
then
Now we must convert hours to minutes:
1.5 hours = 1.5hours (1)
1.5 hours =1.5 hours 
1.5 hours =(1.5)(60) min
1,.5 hours =90min

Answer:
x=90
y=67
Step-by-step explanation:
as the line that bisects the vertical angle of isosceles triangle perpendicularly bisects the base
so x=90
and sum of all sides of triangle is 180 so
90+23+y=180
therefore,y=67
