Answer:

$9

Step-by-step explanation:

set up a proportion where 20% is represented as 20/100 and set it equal to 1.80/x

cross multiply and you should get 180=20x

divide by 20 to solve for x

you then get 9, which is the amount you were looking for

A family drove 180 miles to disneyland. If they left at 10:30
luda_lava [24]

Average speed = Distance/ time

Distance = 180 mi

Time = time(final) - time(initial)

To find time will be easier if we translate am and pm into 24 h scale.

am will  stay the same, so   10:30 am   is 10:30. (initial)

pm will be turned (am time + 12), 3: 00 pm = 3:00 +12 =15:00 (final)

Time = time(final) - time(initial)= 15:00 - 10:30 = 14:60 - 10:30 =4h 30 min

4h + 30 min = 4h + 1/2 h= 4.5 h (time)

Average speed = Distance/ time = 180 mi / 4.5 h = 40 mi/h

Answer is 40 mi/h.
