Question

26. You travel 60 kilometers in 1.5 hours. What is your average speed?

30. You ride in a train for 175 miles at an average speed of 50 miles per hour. How many hours does the trip take?

42.Convert 6ft/sec. to miles per hour

48. The elevator in the Washington Monument takes 60 seconds to rise 500 feet. What is the average speed in miles per hour?

Answer 1

26.  60/1.5=40mph

30.  175/50=3.5 hours

42.  6ft/sec, 60 secs in a minute means 6*60=360ft/minute

so...60min/hr means 360ft*60=21,600ft/hr-convert that to miles, you can do it.  there are 5,280 feet in a mile

48.  same thing along the lines of number 42-try it.

Answer 2

ill give you the formaulas you figure it out.

d = distance

t = time

as = average speed

everything else is self explanatory.

26.  d / t = as ___  Kph

30.  d / as = t ____ hrs

42.  ft  x  seconds in a min = ft/min

      ft  x  minutes in an hour = ft/hour

      ft  /   ft in a mile  = miles/hr

48.  500 ft in 60 secs = 500ft/min

      ft  x  mins in an hour = ft/hr

      ft  /   ft in a mile = miles/hr

Answer 3

26. divide 60km by 1.5 hours to find the average speed (km/h)

30. divide 175 miles by 50 miles per hour to find total hours

42. multiply 6ft by 3600

48. 1 minute is 500ft.. so multiply to get 1 mile
