Answer:
3cd+3 1/3c- 3d
Step-by-step explanation:
6 cd+ 3 c- 7 d- 3 cd+ 4d+ 1/3 c
6 cd - 3 cd = 3 cd First term
3c + 1/3c = 3 1/3c Second Term
4d - 7d = -3d Third Term
Combine all terms to get:
3cd+3 1/3c- 3d
Answer:
40 mph.
Step-by-step explanation:
Suppose grandma's house is 30 miles away (any distance would do but 30 is convenient).
Speed = distance / time
time = distance / speed
Time to get there = 30/60 = 1/2 hour.
Time to get back = 30/30 = 1 hour
Average speed = total distance/ total time
= (30 + 30) / ( 1 + 1/2)
= 60 / 1.5
= 40 miles per hour.
You cannot take the average of the speeds directly
(60+ 30)/2 = 45 is not correct as you cannot average ratios ( speed is a ratio).
