Speed of car A is given as

now we need to convert it into SI units
1 miles = 1609 m
1 hour = 3600 s
now we have

now its distance from Bambi is given as

time taken by it to hit the Bambi



Now other car is moving at speed 50 mph
so its speed in SI unit will be


now its distance from Bambi is given as

as we know that 1 feet = 0.3048 m

now the time to hit the other car is


So Car B will hit the Bambi first
