Answer:
Your answer would be C because a trinomial consists of 3 parts!
Step-by-step explanation:
Answer:
20+9
Step-by-step explanation:
First, 300/5 = 60
so, 500/60 = 8.3
so he'd need to work around 8 hours
Distance = 30 mph * time
distance = 4 mph * time
distance = 30 mph * t
distance = 4 mph * (17-t)
Since distance is equal then
30 mph * t = 4 mph * (17-t)
30t = -4t + 68
34t = 68
t = 2 hours
We see the return trip time is (17 -t ) which is 15 hours.
The beginning trip time is 2 hours.
Double Check
Beginning trip = 30 miles * 2 = 60 miles
Return trip = 4 miles * 15 = 60 miles.
