Slow and steady wins the race. The leather back sea turtle is the fastest known reptile, with a maximum speed of 21.9221.9221, point, 92 miles per hour(mph)
Which of the following equations, where d is distance in miles and t is time in hours, represents a speed that is less than that of the leather back sea turtle?
Choose all answers that apply:
(Choice A)
d=2.192t

(Choice B)
d=20t

(Choice C)
d=22t

(Choice D)
d=30t

Since units for distance and time are all measured in miles and hours respectively, we can simply compare the values of the options given with the leatherback turtle speed and express if the value is lower or not. We must pay special attention to the decimal separator in some cases.

Leatherback sea turtle: d = 21.92t

a. d = 2.192t is less than 21.92t

b. d = 20t is less than 21.92t

c. d = 22t is more than 21.92t

d. d = 30t is more than 21.92t

a (2.192t) and b (20t)

What is an equation?

An equal statement between two equations consisting of an equation, a variable, and/or a number. In essence, equations are problems, and the evolution of mathematics has been driven by attempts to find answers to these problems in a systematic way.

An equation is a mathematical statement consisting of two equations connected by an equal sign. For example, 3x – 5 = 16 is an equation. Solving this equation gives the value of the variable x as x = 7.
