Answer 2

Part (a)

distance = rate*time

rate = distance/time

rate = 84/4

rate = 21

Answer: 21 mph

==================================================

Part (b)

distance = rate*time

distance = 21*7

distance = 147

Answer: 147 miles

==================================================

Part (c)

distance = rate*time

time = distance/rate

time = 57/21

time = 2.71428571428571

time = 2.714

Answer: Approximately 2.714 hours
