Answer :
It can go 78.75 or 78 3/4 meters in one second. Since it gave you 2/3, you divide 52.5 by 2, and then multiply it by 3.
An airplane can ascend at a rate of 78.75 meters in one second or 78 3/4 meters in one second.
What is unitary method?
The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
An airplane can ascend at a rate of 52 1/2 meters in 2/3 of a second
52 1/2 m in 2/3 of a second
X in 1 second
[tex]\frac{2}{3} X = 52.5[/tex]
⇒ [tex]X = \frac{52.5}{\frac{2}{3} }[/tex]
⇒ X = [tex]\frac{52.5(3) }{2}[/tex]
⇒ X = 78.75 m
It can go 78.75 meters in one second or 78 3/4 meters in one second.
Hence, An airplane can ascend at a rate of 78.75 meters in one second or 78 3/4 meters in one second.
