Answer:
<h2> 65km</h2>
Step-by-step explanation:
Step one:
given
we are told that the distance is 3.25cm on the map
the scale is 1cm to represent 20km
Required
the actual distance
Step two
if 1cm represent 20km
then 3.25cm will represent x km
cross multiply we have
x=2.35*20
x= 65km
Hence, the actual distance between these two cities in kilometers 65km
71.4 and to check just multiply 71.4 times 5 and it'll get 357
Falling at the rate of 2.5 m/s for 45 seconds, the anchor fell
(2.5 m/s) x (45 s) = 112.5 meters .
If it wound up only 40 meters underwater, then it must have fallen
(112.5 m - 40 m) = 72.5 meters
from its storage position on the big cruise ship,
before it ever reached the water.
Since it was falling at the rate of 2.5 m/s, it took
(72.5 m) / (2.5 m/s) = 29 seconds
to get down to the water surface after it started dropping.
