Answer:
15 seconds
Step-by-step explanation:
Simply assume that total length to be covered be 'L'.
Now , of total length L is covered in time
.
We know distance traveled =speed×time
Let Object's velocity be V
Using this
Thus, velocity in terms of total length is
Now,
To cover total length L time needed is
Time taken =15 seconds
Answer:
Option B
Step-by-step explanation:
Since, number of calories 'C' burned is proportional to the number of minutes (m) given to the exercise,
C ∝ m
C = km
Where k is the proportionality constant.
From the table attached,
For C = 250 calories and m = 30 minutes,
250 = 30k
k =
=
Therefore, equation representing this situation will be,
C =
Option B will be the correct option.
Answer:
22 units²
Step-by-step explanation:
1/2b*h=area
You can either count the units or use the distance formula.
b = 4 units
h = 11 units
area = (1/2*4)*11 = 22 units²
