Answer:
7.23km/h
Step-by-step explanation:
Speed = distance/time
Given
distance = 6.36km and
Time = 53minutes
Convert 53minutes to hour.
60 minutes = 1 hour
53 minutes = x hour
Cross multiply
X hour x 60 = 53
Xhour = 53/60
X = 0.88 hour
Therefore
Speed = 6.36km /0.88hr
= 7.23km/h
Answer:
60
Step-by-step explanation:
60 plus 60 plus 60 is 180
has to add up to 180
You must score a minimum of 190 in the fourth test to get an A for the course
The first three tests are worth 100 points while the fourth is worth 200 points
The 1st score = 84
The 2nd score = 92
The third score = 89
Let the fourth score on a 200 scale = x
The fourth score on a 100 scale = x/2 = 0.5x
Average = (1st score + second score + third score + 4th score) / 4
Average = (84 + 92 + 89 + 0.5x) / 4
To get an A:
Average ≥ 90
(84 + 92 + 89 + 0.5x) / 4 ≥ 90
265 + 0.5x ≥ 360
0.5x ≥ 360 - 265
0.5x ≥ 95
x ≥ 95/0.5
x ≥ 190
You must score a minimum of 190 in the fourth test to get an A for the course
