First, you have to know what is 50km in terms of feet.
1 metre = 3.281 feet approx.
In changing speed from km/hr to m/s, we divide the speed in km/hr by 3600 as 1 hr = 60 min x 60 s.
So, 50km/hr = 13.89 m/s approx
Changing speed from m/s to ft/s, we have to multiply by 3.281.
So, speed of 50km/hr = 13.89m/s x 3.281ft/m = 45.57ft/s approx.
Alternatively, 50km = 50 000 m = 164 050 ft
So 50km/hr = 164 050ft/hr = 164 050 ft/hr x 1/3600 hr/s = 45.57ft/s approx.

50 kilometers = 50000 meters.
1.00000 Meter = 3.28084 Feet
1 hour is 3600 seconds.
So, we have
50 x 1000 x 3.28084 / 3600 = 45.567222...
So, let us say 45.567 feet per second

First convert 50km/hr to m/s by multiplying it with 5/18. That gives you speed of13.89 m/s. Now 1 m = 3.28 feet so multiply 13.89 with 3.28 to get 4.56 feet/s.

v = 50 km / hr
v = 50 (1000) (3.28) / 3600 = 45.5555 ft / sec

why dont you solve it yourself?
letting other people answer these types of questions for you wont help...

50km/h=50kmx1000m/kmx3.28ft/m/3600s=50x32.8/36ft/s
=45.56ft/s
