Ricardo and john start swimming from the same location. ricardo starts 15 seconds before john and swims at a rate of 3 feet per second. john swims at a rate of 4 feet per second in the same direction as ricardo. which equation could you solve to find how long it would take john to catch up with ricardo?
a. 4t+3=3t
b. 4t+60=3t
c. 3t+3=4t
d. 3t+45=4t

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions
