A) 25 Km/hr |
B) 28 Km/hr |
C) 40 Km/hr |
D) 35 Km/hr |
D) 35 Km/hr |
Let the speed of first car = 7x
2 nd car = 8x.
According to the question
\(\Large 8x = \frac{200}{5} = 40 \left[ using \ speed = \frac{distance}{time}\right]\)
\( \Large x = \frac{40}{8} = 5\)
Speed of first car = 7x = 7 X 5 = 35 Km/hr
