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

Step-by-step explanation:
Hey!
------------------------------------------------
Surface Area Formula: 2LW * 2LH * 2WH
------------------------------------------------
2LW:
5 x 1 = 5
5 x 2 = 10
------------------------------------------------
2LH:
4 x 1 = 4
4 x 2 = 8
------------------------------------------------
2WH:
5 x 4 = 20
20 x 2 = 40
------------------------------------------------
Surface Area:
40 + 8 + 10= 58
------------------------------------------------
Answer:
D) 58 cm2

Hope This Helped! Good Luck!
Answer:
11/24
Step-by-step explanation:
7/8 + 11/12 + 3/4 + x = 3 km
7*3/8*3 = 21 / 24
11*2 / 12 * 2 = 22 /24
3*6 / 4*6 = 18/24
21/24 + 22/24 + 18/24 + x = 3
61 / 24 + x = 3
x = 72/24 - 61/24
x = 11 / 24
Tim has to run 11/24 of the race
Check the picture below
if that red segment, GJ, is parallel to the AE base segment of the triangle, then, the segment GJ is the midsegment of the triangle, and by the side-splitter theorem, those two triangles are similar.
