Answer:

Step-by-step explanation:

ΔABD ≅ ΔCBD .

So AD = DC

8x - 4 = 3x + 1 {add 4 to both sides}

8x = 3x + 1 + 4

8x = 3x + 5 {subtract 3s from both sides}

8x - 3x= 5

5x = 5 {divide both sides by 5}

x = 5/5

x = 1

It takes Dwight 1 1/3 hours to run the sunshine trail. Mike 3 1/5 hours to walk the same trail. How many times as long does it t

Anit [1.1K]

For this case we convert the mixed numbers to fractions:

Dwight: $1 \frac {1} {3} = \frac {3 * 1 + 1} {3} = \frac {4} {3} = 1.33$

Mike: $3 \frac {1} {5} = \frac {5 * 3 + 1} {5} = \frac {16} {5} = 3.2$

It is observed, that in fact, Mike takes more time to travel the road.

We subtract to know how much more time it takes Mike:

$\frac {16} {5} - \frac {4} {3} = \frac {48-20} {15} = \frac {28} {15}$

So, Mike takes $\frac {28} {15}$ hours more than Dwight to walk the road.

Answer:

Mike takes $\frac {28} {15}$ hours longer than Dwight to walk the road.
