270kilometers
Step-by-step explanation:
To find the distance, all you have to do is the speed · time
In these types of distance time and word problems, you multiply the other factors, 90 and 3, The time(T) · The speed(S)
So. 90(S) · 3(T) = 270(D)
Answer: Length: 4, width: 6
Step-by-step explanation:
Let the length be x and width be y
Then x=2y-8 and xy=24
Substitute to get 2y-8 * y = 24, so 2y^2-8y=24 or y^2-4y=12, then solve to get y=6 or y=-2. Since width is positive y=6.
Substitute y=6 into xy=24 to get x=4.
Length: 4, width: 6
