If Joe drives 50 mph for 0.5 hours and then 60 mph for 1.5 hours, then how far did he drive?
1 answer:
Answer:
115 mi
Step-by-step explanation:
speed = distance/time
distance = speed * time
0.5 hours at 50 mph
distance = 50 mph * 0.5 h = 25 mi
1.5 hours at 60 mph
distance = 60 mph * 1.5 h = 90 mi
total distance = 25 mi + 90 mi = 115 mi

y=1/2r hope i helped
let g(x) = x^2+2
let f(x) = 9/x
f(g(x)) is therefore equal to f(x^2 + 2) which is equal to 9/(x^2+2).
i think it's 790,000 or 800,000 i hope i helped
The graph shows the solution to be (x, y) = (-1, 3).
