Answer:
The formula to enter in E14 is as follows:
=DAYS(D14,$E$10)
Explanation:
Required
Formula to calculate the number of days between E10 and D14
The syntax to do this is:
=DAYS(end_date,start_date)
So, we have:
=DAYS(D14,E10)
The question requires a mix of relative and mixed references because cell E10 will be constant in calculating the difference for dates in other cells.
In other words, the initial date is constant for all
So, the update formula is:
=DAYS(D14,$E$10)
Notice the $ between in E10; this represents mixed referencing
When dragged to E15 till E68, the formulas in the respective cells will be:
=DAYS(D15,$E$10) .............................. =DAYS(D68,$E$10)
let's say they catch-up to each other after t hour.
so
in t hour distance travelled by Renee
d = speed × time = 50t
in t hour distance travelled by Kim
d = speed × time = 60(t-1) + 0×1 = 60(t-1)
Note: here kim didn't covered any distance in first hour and in rest t-1 hour it travelled all distance
now.as distance travelled by both is same so
60(t-1) = 50t
60t -60 = 50t
adding 60 both sides
60t = 50t+60
subtracting 50t both sides
60t -50t = 50t+60 - 50t
10t = 60
dividing by 10 both sides
t = 60/10 = 6
so in 6 hour both will catch-up to each other
