Answer:
Step-by-step explanation:
Time taken for task 1:
Distance= 750m= 0.75 km
Speed= 10 km/hr
Time taken1= S (distance)/ V (speed)= 0.75/10= 0.075 hr= 4 mins and 30 sec
Time taken for task 2:
t2=S/V= 20/85= 0.24 hr= 14 mins and 24 sec
Time taken for task 3:
t3= S/V = 5/14= 0.36 hr= 21 mins and 36 sec
Total time took:
T1 +T2+T3= 40 mins and 30 second (approximately)
Answer:
The ratio 2 1/2 to 6 1/2 is

Step-by-step explanation:
Ratio:
In mathematics, a ratio is a relationship between two numbers indicating how many times the first number contains the second.
It is also the Fraction
.
For example, if a bowl of fruit contains eight apples and six kiwis, then the ratio of apples to kiwis is eight to six.
i.e 8:6, which is equivalent to the ratio 4:3.
Now here,

Ratio of 2 1/2 to 6 1/2

OR

Answer:
Both
1 ≥ 2x
and
6x ≥ 3 + 8x – 4
Step-by-step explanation:
Correct representations are representations which are equivalent and represent the exact same relationship. To find these, you can simplify the inequality.
6x ≥ 3 + 4(2x – 1)
6x ≥ 3 + 8x - 4
6x ≥ 8x - 1
-2x ≥ -1
2x ≤ 1
x ≤ 1/2
