Answer:
don't understand
but mean = <u>summation x</u>
total number
15=<u>7+4+5+2x+11</u>
5
15=<u>27+2x</u>
5
multiply both sides by 5
15×5=<u>2</u><u>6</u><u>+</u><u>2</u><u>x</u> ×5
5
75=26+2x
75-26=2x
<u>49</u>=<u>2x</u>
2. 2
x= 24.5

Answer:
31.46 km/hr to the nearest 100th
Step-by-step explanation:
10:55 to 11:00 is 5 min
11:00 to 12:00 is 60 min
12:00 to 12:38 is 38 min
That's 5 + 60 + 38 = 103 min = 103/60 hr. = t
d = rt
54 = 103/60(r)
r = 54(60)/103 =31.46 km/hr to the nearest 100th
