Answer:
y = 6x
Step-by-step explanation:
Equation representing the relation between duration of work and earning is,
y = kx
Here, y = earnings
x = Working hours
k = Proportionality constant
By substituting the values in the given equation,
x = 25 hours
y = $150
150 = k(25)
k = 6
Therefore, equation modeling the situation will be,
y = 6x

Answer:160 miles
Explanation:
You can work out this type of question by using the 'unitary' method, which means finding out how much for ONE.
If you set out the steps with short sentences it will be clearer.
On 15 gallons, a car can travel 400 miles÷15↓
On 1 gallon, a car can travel 400÷15=262
miles
Once you know the distance travelled on 1 gallon of fuel, you can work out the distance travelled for any number of gallons.
On 6 gallons the car can travel
