Respuesta :
Speed of car A is given as
[tex]v_a = 70 mph[/tex]
now we need to convert it into SI units
1 miles = 1609 m
1 hour = 3600 s
now we have
[tex]v_a = 70 *\frac{1609}{3600} = 31.3 m/s[/tex]
now its distance from Bambi is given as
[tex]d_a = 350 m[/tex]
time taken by it to hit the Bambi
[tex]t = \frac{d}{v}[/tex]
[tex]t = \frac{350}{31.3}[/tex]
[tex]t = 11.2 s[/tex]
Now other car is moving at speed 50 mph
so its speed in SI unit will be
[tex]v_b = 50* \frac{1609}{3600}[/tex]
[tex]v_b = 22.35 m/s[/tex]
now its distance from Bambi is given as
[tex]d_b = 590 feet[/tex]
as we know that 1 feet = 0.3048 m
[tex]d_b = 590*0.3048 = 179.83 m[/tex]
now the time to hit the other car is
[tex]t_2 = \frac{179.83}{22.35}[/tex]
[tex]t_b = 8.05 s[/tex]
So Car B will hit the Bambi first
