Answer:
4.8 hours
Step-by-step explanation:
Distance = speed × time
If Tim drove 4 hours at 60 miles per hour
Than he drove a total of 4×60 miles
He drove 240 miles
Time = distance ÷ speed
If he drove 240 miles at 50 miles per hour
Than he took 240÷50 hours
He took 4.8 hours (4 hours and 48 minutes)

Answer:
f(g(x)) = 72x^2+1
Step-by-step explanation:
f(x) = 2x^2 +1
g(x) = -6x
f°g(x) means f(g(x))
Take g(x) and substitute it in for x in f(x)
f(g(x)) = 2(g(x))^2 +1
=2(-6x)^2 +1
=2(36x^2) +1
=72x^2 +1
