Question:

Lisa walks at an average speed of 6 km/h for 15 hours.

Dan completes the same distance in an hour. Calculate Dan's average speed.

Answer:

$Speed = 90km/hr$

Step-by-step explanation:

Given

Lisa:

$Speed = 6km/hr$

$Time = 15\ hr$

First, we calculate the distance covered by Lisa:

$Distance = Speed * Time$

$Distance = 6km/hr * 15\ hr$

$Distance = 90km$

So, Dan distance can be represented as:

$Distance = 90km$ --- Dan completes the same distance as Lisa

$Time = 1\ hr$ -- Time to complete the distance

Dan's average speed is:

$Speed = \frac{Distance}{Time}$

$Speed = \frac{90km}{1\ hr}$

$Speed = 90km/hr$

<em>Hence, Dan's average speed is 90km/hr</em>

12 r - 18 = 13 r + 18

First you want to isolate the variable, do this by adding 18 to both sides. You're left with 12r = 13r + 36, then subtract 13r to get the variables alone. You're then left with -1r = 36, multiply by -1 to remove the negative. The final result would be (1) r = 36.
