$\huge\fbox\pink{✯Answer✯}$

• refer the attachment I solve this problem in my notebook

$\huge\boxed{\fcolorbox{purple}{ink}{Consider:}}$

• Let the speed of plane is x km/hr
• Total distance =1500 km
• Time taken 1500/x

$\huge\boxed{\fcolorbox{purple}{ink}{Then:}}$

• Increased speed
• = (x+100 km/hr )
• d= 1500 km

$t2 = \frac{1500}{x + 100}$

$t = 30 =t2$

$t1 - t2 = 30 \: minutes$

$\frac{1500}{x} - \frac{1500}{x + 100} = \frac{1}{2}$

see the details step in attachment

after solving that steps we get

$\huge\boxed{\fcolorbox{red}{ink}{SOLUTION:}}$

$x = 500 \: km \: per \: hour$

$\huge\boxed{\dag\sf\red{Thanks}\dag}$
