Answer:
60
Step-by-step explanation:
To find the range, you subtract the largest number and the smallest number.
Largest number: 80
Smallest number: 20
80-20=60
2 or 2/1

Answer:
(a)81 yards (b)27 seconds
Step-by-step explanation:
Let Shontal distance to the point where he overtakes Diego=x
Since Diego is given a head start of 27 yards, his distance to the point where he is overtaken by Shontal=x-27
Diego hops at a rate of 2 yards per second.
Shontal hops 3 yards per second.
Now, Time Taken=Distance ÷ Average Speed
- For Diego, Time Taken = (x-27) ÷ 2
- For Shontal, Time taken = x ÷ 3
At the point where Shontal overtakes Diego, their time taken are equal.
Therefore:
Cross multiplying
3(x-27)=2x
3x-81=2x
3x-2x=81
x=81 yards
(a) Therefore, Shontal will have to hop 81 yards
(b)Recall, for Shontal,
Time taken = x ÷ 3 = 81 ÷ 3 =27 seconds
It will take Shontal 27 seconds to overtake Diego.
The answer is f^-1(x)=x/3-14/3
