He will swim 180m if he stays at a constant rate of 30m/min

Explanation:

First I’m going to use 6 min for the 5min 60s

Then if he swims 30m/min then I’m 6min, 30•6 he’ll swim 180m

Hope this helps!

**Answer:**

**Explanation:**

the resistance of a electrical device

R = V² / P where V is volt and P is power .

The devices are in parallel so same volt will apply on them

So R₁ = 12² / 32.5 = 4.431 ohm

R₂ = 12² / 2 x 10³ = .072 ohm

when they are in series

Common Current in them = 12 / 4.431 + .072

= 2.6649 A

power consumed by first device when they are in series

= current² x resistance

= 2.6649² x 4.431 = 31.46 W

power consumed by other

= 2.6649² x .072 = .511 W

**Answer:**

The effort distance (also sometimes called the “effort arm”) is shorter than the resistance distance. Mechanical advantage = |Fr/Fe | where | means “absolute value.” Mechanical advantage is always positive.

We know that

Distance = speed x time

Let w be the time Brad spent walking. The time spent jogging will be 1 - w

6 = 5w + 9(1 - w)

w = 0.75 hours

Distance walked = 0.75 x 5

= 3.75 km

**Answer:**

250 m

**Explanation:**

Since North and East are 90 degrees from each other, we can treat this as a right-angled triangle, with the distance in each direction being the sides and the distance from the starting point being the hypotenuse.

Hence, sqrt(150^2+200^2) = 250 m.
