Answer:
p + q = 20
Step-by-step explanation:
Given the lines intersect at (1, 1 ) then x = 1 and y = 1 make the equations true.
Consider
px = 12 with x = 1
p = 12
Consider
2x + qy with x = 1 and y = 1
2 + q = 10 ( subtract 2 from both sides )
q = 8
Hence p + q = 12 + 8 = 20
First of all you need to work out 20 minutes in hours, this can be done by dividing 20 by 60:
20/60 = 1/3
Then you need to divide 15 by 1/3 to get the final speed:
15 / 1/3 = 45 miles per hour
He will need to be traveling at 45 miles per hour,
Hope this helps! :)
