You can know that it is wrong because by multiplying 6, which is the rounded version of 6.27, by 7 that you will get 42, which is the approximate answer. 438.9 is not even close to thatanswer

120/5 = 24
75/5 = 15
So the dimensions of the scale drawing would be 20 units by 75 units.
Hope this helps.

Step-by-step explanation:
speed is constant at 17 mph
Distance covered after one hour = 17 miles
Distance between port and San Francisco = 3 miles
Speed at which distance changes 1 hour after leaving port :
r² = 17² - 3²
r² = 289 - 9
r = √280
r = 16.733
= 16.7 (nearest tenth )
