Question

the distance between two places is 2500 km if the aeroplane decreases its speed by 250 kilometre per hour then it would have taken 5 hours more find the initial speed of the aeroplane​

Answer 1

Answer:500km/hr.

Step-by-step explanation:

Let the time taken be x hours. And be a km/hr.

Distance =T*S

2500=x*a

In new case,

2500=(x+5)*(a-250)

2500=ax-250x+5a-1250

As 2500, is commen in both cases.

ax-250x+5a-1250=ax

-250x+5a=1250

-50x+a=250

In the given case, the only possible value of both the values are x=5 and a=500km.
