Solve in a calculator.
= 78.5
Answer:
d distance
Step-by-step explanation:
So, in 240 miles can be made by 2 hours.
Do this equation:
240 × 2 = 480 / 4 hours.
You cannot do 3 because it won't fit another 240 miles.
Next, subtract the 480 miles from 600 miles.
600 - 480 = 120
Also, if you would've divided by 2 hours.
240 ÷ 2 = 120 / 1 hour
Add the hours.
4 + 1 = 5 hours
It takes 5 hours to travel 600 miles by the small plane.
Umm not really sure but I'd go with A. You may need another source to double check my answer, I'm probably wrong.
Answer:
Step-by-step explanation:
The gradient is the the slope of the equation.
5x - 2y = 12
Making y as subject of formula
2y = 5x - 12
Dividing through by 2
y = 5x/2 - 12/2
y = 5x/2 - 6
And comparing with y = mx + c
Where m is the slope = 5/2
