Firstly, subtract both sides by 7x: 15+x=-8

Next, subtract 15 on both sides and <u>your answer will be x = -23.</u>

It took Jack 2 hours to paddle 6.4 km upstream on the Black River to the giant's castle. The speed of the river is 1.8 km/h. How
Lostsunrise [7]

To find the time Jack takes to cross Swan Lake, his average speed is required:

The time it will take Jack to cross Swam Lake is <u>0.5 hours</u>

Reason:

Time it took Jack to paddle 6.4 km upstream, t = 2 hours

Distance Jack paddled, d = 6.4 km

The given speed of the Black River, <em>v₂</em> = 1.8 km/h

The width of the lake, w = 2.5 km

The time it will take Jack to cross Swan Lake

Let <em>v₁</em>, represents Jack's speed, we have;

v_1 - v_2 = \dfrac{d}{t}

Therefore;

v_1 - 1.8 = \dfrac{6.4}{2} = 3.2

v₁ = 3.2 + 1.8 = 5

  • Jack's speed, v₁ = 5 km/h

Time \ to \ cross \  the \ lake , \ t_S = \dfrac{w}{v_1}

t_S = \dfrac{2.5 \, km}{5 \, km/h}  = 0.5 \, hr.

The time it will take Jack to cross Swan Lake, t_S = <u>0.5 hours</u>
