Answer 1

Hey User !

=) "

Car I x kmph Car II x+ 5 kmph

They are moving away from each other

So add up their speedCombined speed = x+x+5 (2x+5)

Time = 5 hours

Distance = 425 km

Distance = speed * time

(2x+5 )* 5 = 425

10 x + 25 = 425

10 x = 425 + -25

10 x = 400 / 10

x= 40 kmph Car I

Car II 40 + 5 = 45 kmph

Hope , It Helps .
