The average speed is the distance divided by the time.
Total distance:
12.8 miles + 17.2 miles = 30 miles
Total time:
noon - 9:00 a.m. = 3 hours
6:00 p.m. - 1:00 p.m. = 5 hours
Total time = 3 hours + 5 hours = 8 hours
average speed = 30 miles / 8 hours = 3.75 miles per hour
Answer:

Step-by-step explanation:

Answer:
366
Step-by-step explanation:
A garden table and bench cost 816 when combined together
The garden table cost 84 less than the bench
Therefore the price of the bench can be calculated as follows
x + (x+84)= 816
2x+84= 816
2x= 816-84
2x= 732
Divide both sides by 2
x= 732/2
= 366
Hence the price of the bench is 366
Answer:
a = 29
u = 12
Step-by-step explanation:
32 + 7u + 9 + 2a - 3 = 3a + 7u + 9
32 + 2a - 3 = 3a
a = 29
3(29) + 7u + 9 = 180
7u = 180 - 96
7u = 84
u = 12
