a.) The Clark family will drive from Boston to Miami. They plan to drive 8 hours each day at an average speed of
50 mph. About how many days will the trip take? Round the answer to the nearest day.
b.) There is highway construction between Washington, DC and Wilmington, causing the Clarks to drive 40mph
instead of 50 mph. How much longer will this make that part of the trip? Round to the nearest tenth.
c.) If the Clarks drove from Wilmington to Jacksonville in 7 hours, find their average rate of speed.
Problem #4

requested units of measure. Think about the appropriate
conversions. Show all of your work!
a.) A cheetah can run at a speed of 1.2 miles/minute.
Convert the cheetah’s speed to miles per hour.
b.) A house fly flies at a speed of 440 feet/minute.
What is its speed in miles per hour?
(1 mile = 5280 feet)
c.) A snail can move at a speed of 20 inches/minute.
How many times faster is the cheetah than the snail?
