Answer: speed is 540 km/h
Step-by-step explanation: Lets mark speed as v.
Because distenace is same, you can mark 6 h · 900 km/h = 10 h · v
and v = 5400 km / 10 h = 540 km/h.
Or using inverse proportions : 10 h / 6 h = v / 900 km/h .
Before multiplying you turn lastproportion around :
10 h / 6 h = 600 km/ h / v ,which gives 10 v = 6 · 900 km/h
and result is same

Answer:
The flow rate in dextrous solution is 0.117 litres per hour
Step-by-step explanation:
Given:
The volume of fluid which passes per unit time = 1.17 Litres
Time Period = 10 hour
To Find:
The Flow rate per hour = ?
Solution:
Flow rate is defined as rate at which the "{volume of fluid which passes per unit time"
Here the Flow rate is = 
On substituting the values
The Flow rate is =
The flow rate is 0.117 litres per hour
Thus 0.117 litres of dextrous solution flows per hour.
The right answer is Option C : 5
Step-by-step explanation:
Let,
The numerator of fraction = x
The denominator of a fraction is 10 more than its numerator.

When 1/3 is added to this fraction,

the resulting fraction’s denominator is three times the denominator of the original fraction its numerator is 15 less than its denominator

Therefore, it becomes

Taking LCM on left side

Multiplying both sides by 3(x+10)

The numerator of original fraction is 5.
The right answer is Option C : 5
