Juan will jump 40 times in 50 seconds.
The unitary method is a concept wherein a problem is solved first by finding the value of a single unit and then multiplying the single unit value to find the necessary answer.
Here, we are given that
Juan jumps 24 times in 30 seconds
Thus, the number of times he will jump in 1 second is given by-
24/ 30 = 0.8
Thus, he jumps 0.8 times in 1 second
Now, we need to find the number of times he jumps in 50 seconds. We can do so simply by multiplying the number of times he jumps in 1 second by 50.
Thus, number of times he jumps in 50 seconds = 0.8 * 50
= 40
Therefore, Juan jumps 40 times in 50 seconds.

The diameter of the coaster is 5 cm.
Step-by-step explanation:
Given,
The area of the circle = 19.63 sq inch
To find the diameter, we need to find the radius
Formula
The area of a circle with radius(r) = π
sq cm
According to the problem,
π = 19.63
or, = 
= 6.2459
or, r = 
= 2.499 (approx)
= 2.5 cm
Hence the diameter of the circle = 2 × 2.5 cm = 5 cm
