x = 3
Step-by-step explanation:

You have to convert kilograms to grams or grams to kilograms. Conversion is; Kilo Hecto Deca (base-which in this case is grams) deci centi milli.
Let the time = x
Distance = Speed x time
One train is 75x, the other train 85x
Add together to equal total distance:
75x + 85x = 384
Simplify:
160x = 384
Divide both sides by 160:
x = 384 / 160
x = 2.4 hours
Answer:

Height of sun Innthe sky:
Shadow of flower / height of flower
= 4/3 = 1.333333
Height of tree:
Shadow of tree / height of sun
26 feets / 1.33333
= 19.5 feets
Hence, height of tree = 19.5 feets
