Step-by-step explanation:

a) r=d/t ( same as formula of speed)

b) r= 665280/3=221760 feet/hr

c) distance in miles = 665280/5280= 126

so r=126/3 = 42 miles/hr

d) i think using miles makes more sense cz using feet will result in greater number of values so there is a greater chance of human error

Adding answer so you can mark the original answer as brainliest!

Part A: r = d/t > 221,760 = 665,280/3

Part B: 221,750 feet/hour

Part C: 126 miles/hour (divide speed value by 5280

Part D: Miles makes more sense in this scenario because it is a larger unit of measurement and the dolphin travels a long distance.
