Aneesha travels at a rate of 50 miles per hour. morris is traveling 3 feet per second less than aneesha. which is the best estimate of the speed morris is traveling?

If Aneesha travels at a rate of 
50 miles1h 
and  1mile=5280ft,     therefore 50 miles = 264000 ft
and 1 h =3600 seconds we can say that Aneesha travels

264,000 ft in 3600 seconds or 
264,000/3600= 73.33 ft/s

Morris travels 3 ft per second less than her
so 73.33-3=70.33 ft/s for  Morris

Can u send a screenshot of it? !
