The weight m of an object on mars varies directly as it's weight e on earth. a person who weighs 95 lb on earth weighs 38 lb on mars. how much would a 100 lb person weight on mars

A person weighing 100 lb on Earth will weigh 40 lb on Mars.

Step-by-step explanation:

Given:

The weight M of an object on Mars varies directly as it's weight E on Earth

represents weight of an object on Mars

represents weight of an object on Earth

So, it is given that directly varies with .

∝

which can be written as

where represents the constant of proportionality.

Given a person weight 95 lb on Earth weighs 38 lbs on Mars.

So, we can evaluate using the given weights.

Dividing both sides by 95.

∴

To find the weight of a person on Mars, given that he weighs 100 lb on Earth.

substituting value of

∴

Thus, a person weighing 100 lb on Earth will weigh 40 lb on Mars.

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.
