Question

A Helicoptes coves 800km in the 1hr
The dictance
will it coves in 5 hous
​

Answer 1

Step-by-step explanation:

according to the question

x600−x+20600=5

x2+20x600x+12000−600x=5

600x+12000−600x=5x2+100x

5x2+100x−12000=0

x2+20x−2400=0

x2+60x−40x−2400=0

x(x+60)−40(x+60)=0

(x+60)(x−40)=0

x=40km/hr since speed cannot be negative

This is hint according to this you have to do above question.
