Answer:
let time for the race be y minutes
If 32 miles =160 minutes
then 100 miles =y minutes
Cross multiply: (100 miles*160 minutes) = 32 y
y = (100*160)/32 =500
time for the race = 500 minutes
Step-by-step explanation:
(B (4, 7 ) = (1, 12 )
given
B (x, y ) = (x - 3, y + 5 ) , then
B (4, 7 ) = (4 - 3, 7 + 5 ) = (1, 12 )
