Aneesha travels at a rate of 50 miles per hour. Morris is traveling 3 feet per second less than Aneesha. Which is the best estim
goldfiish [28.3K]
If Aneesha travels at a rate of 
50 miles............................1h 
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
