The speed of current will be "4.5 mph" and the rate Pratap can row in still water will be "8.5 mph".

What does "speed" mean in mathematics?

Speed is what it means. the speed of a change in an object's location in any direction.
Speed is defined as the ratio of distance to the amount of time it took to cover that distance.
Speed is a scalar quantity because it just has a direction and no magnitude.

Given:

Distance "26 miles" in time "2 hours".

Let,

Speed of water = y

Pratap speed when rowing in still water = x

As we know,

Speed = distance/time

then,

x + y = 26/2

x + y = 13

x = 13 - y

In return trip took him time "6.5 hours",

x - y = 26/6.5

x - y = 4

By substituting the value of "x", we get

13 - y - y = 4

13 - 2y = 4

2y = 13 - 4

2y = 9

y = 9/4 = 4.5 mph (Rate of the current)

By substituting the value of "y", we get

x = 13 - a

x = 13 - 4. 5 = 8.5 mph (Pratap can row in still water)

The selling price of a refrigerator, is $739.20. If the mark up is 20% of the dealers cost , what is the dealers cost of the ref

Lisa [10]

Mark up percentages are used to increase the prices of items

The dealers cost of the refrigerator is $591.36

<h3>How to determine the dealer cost</h3>

Represent the dealer cost of the refrigerator with x.

Given that the markup is 20% and the selling price of the refrigerator is $739.20, then we have the following equation

x = 739.20 * (1 - 20%)

Evaluate the product

x = 591.36

Hence, the dealers cost of the refrigerator is $591.36
