Use the diagram to find the value of the median of the trapezoid

Option D 14 units.

Step-by-step explanation:

In the given diagram a trapezoid has been given with two bases AB = 7 units and CD = 21 units

We have to find the median of the trapezoid. We know that median of a trapezoid is half of the sum of bases.

So median of ABCD = (AB + CD)

                                 = ( 7 + 21 )

                                 = ( 28 )

                                 = 14 units.

Option D 14 units is the answer.

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles
