Answer: if speed of second car is 200 km/5hr
Explanation:Let speed of 1st car = 7x
and speed of the 2nd car = 8x
According to the question,
8x=2005=40 [using, Speed = Distnce/Time]
Therefore, x=408=5
Therefore, Speed of the 1st car
7x=7×5=35km/h

Answer:
given ratio of speed=8:9
let the ratio of speed = X
speed of 1st car= 8x=S1
speed of 2 car= 9x=S2
Speed= D/T
given
S1/S2= 8x/9x
(D/T1)/(D/T2)=8/9
D/T1 x T2/D=8/9
T2/T1=8/9
so ratio of Time car 1 to Car 2= 9:8
