Answer:

43 minutes

Step-by-step explanation:

<em>Let cycling speed be x and driving speed be y</em>

<u>Equations as per given, considering same distance in both cases:</u>

19x + 8y = 13x + 10y
19x - 13x = 10y - 8y
6x = 2y
3x = y

We see that driving speed is 3 times greater than cycling speed

Then 8 minutes driving = 8*3= 24 minutes of cycling, or 10 minutes of driving = 10*3= 30 minutes of cycling:

19 + 24 = 43 minutes or
13 + 10*3 = 43 minutes is the time to cycle between A and B

$\text{Hello there!}\\\\\text{In this question, we're trying to solve the equation}\\\text{We would use the distributive property and solve after that}\\\\\text{Lets solve:}\\\\-16 + 5n= -7(-6 + 8n) + 3\\\\\text{Distribute the -7 to the numbers inside the parenthesis}\\\\-16 + 5n= 42 -56n + 3\\\\\text{Add 56n to both sides}\\\\-16 + 61n= 42 + 3\\\\\text{Add 16 to both sides}\\\\61n= 42 + 3 + 16\\\\61n= 42 + 3 + 16\\\\61n= 45 + 16\\\\61n = 61\\\\\text{Divide both sides by 61}$
