Answer:

a. 46.89 mph

b. 0.781 mi/min

c. 4126.22 ft/min

d. 68.77 ft/s

e. 1.28 min/mi

Step-by-step explanation:

a. Miles per hour

1. Convert 4 hours and 30 minutes into hours (4.5 hours).

2. Divide the distance traveled by the new time.

MPH = 211 mi / 4.5 hours = 46.89 mph

b. Miles per minute

1. Convert 4 hours and 30 minutes into minutes: (4*60+30) = 270 minutes

2. Divide the distance traveled by the new time

MPM = 211 mi / 270 min =0.781 mi/min

c. feet per minute

1. Use the converted time from part b (270 minutes)

2. Convert the distance traveled from miles to feet: (211*5280=1114080 ft)

3. Divide the converted distance by the converted time

ft/min = 1114080 ft / 270 minutes = 4126.22 ft/min

d. feet per second

1. Convert the time into seconds (270 minutes * 60 sec/min) = 16200 sec

2. Use the converted distance from part c (1114080 ft)

3. Divide the converted distance by the converted time

ft/s  = 1114080 ft / 16200 sec = 68.77 ft/s

e. minutes per mile

1. use the converted time from part b (270 minutes)

2. divide the time by the distance traveled

minutes/mi = 270 min / 211 mi = 1.28 min/mi
