Step-by-step explanation:
3.65<x<3.75

100 - a = 64
36 = 12b
h = 36/9
Speed = distance/time
distance = speed * time
let x = time covered by running
15 = run distance + walk distance
15 = 9(x) + 3(3-x)
15 = 9x + 9 - 3x
15 - 9 = 6x
6 = 6x
x = 1 hour
Therefore:
Running distance = speed * time
RD = 9km/hr * 1 hr
RD = 9km
Click in cell D5.
Then use this formula:
=round(B5/B4, 4)
Example:
b4 = 3.2165
b5 = 21.43
In cell d5, type =round(b5/b4) and press Enter.
cell d5 contains 6.6625.
Answer:
=round(b5/b4, 4)
