Answer:
192 km
Step-by-step explanation:
Lets find the speed the train moves with in one hour
speed = distance/time
speed = 80 4/5 /1
speed = 80 4/5 km/hr
Now, lets find how much distance it will cover in 4 3/4 hours
distance = speed * time
distance = 80 4/5 * 4 3/4
distance = 192 km
The width is w.
The length is 2w-4
By increasing all sides of the deck by 6 feet, the new measurements are
w+6
and
2w+2
The area is (w+6)(2w+2)=
2w^2+14w+12 feet squared
Hope this helps!
