Joe and Hannah leave home at the same time traveling opposite . directions Joe drive 45 mph and Hannah drive 40 mph and how many hours was 510 miles apart

If a train travels 210 miles in 3 hours moving at a constant speed then the speed of the train is 70 miles per hour

What is Speed?

Speed is the time rate at which an object is moving along a path,

Given that a train travels 210 miles in 3 hours moving at a constant speed.

We have to find the speed of the train in miles per hour .

Speed= Distance/time

Distance = 210 miles

Time = 3 hours

Plug in these values in the formula

Speed =210/3

=70 miles per hour

Hence, if a train travels 210 miles in 3 hours moving at a constant speed then the speed of the train is 70 miles per hour

So @mathmate deleted my comment because "I wasn't explaining my answer" well I did

I clearly stated that you have to make educated guess and I showed how I GOT my answer

so i guess here is my "proper" answer

There is no specific formula for this, so you can make an educated guess

for example:

13*5 = 65 (this isn't right because we need a minimum of 114)

so we continue the guessing

I then next tried

13*9

I got 117,

117 is more than 113

making 9 the minimum amount of rows for the hotel parking lot

there ya go @mathmate is that clear enough?

He experiences a gain of 27 from the two more movies, resulting in a net utility gain of 7. In other words, José might feel happier with the two movies instead of the fourth T-shirt.

To find the total profit or loss for each color of T-shirt, you need to analyze the given expenditures and gain.

Let's assume the fourth T-shirt to which José gives up was of a particular color.

According to the information, this step frees up $14. José spends that money to buy the first two movies at the cost of $7 each. Therein exists the loss or gains.

Based on Table 6.2, the marginal utility of the fourth T-shirt, i.e., the satisfaction José gets from it, is determined to be 18 utils.

By giving up this T-shirt, he experiences a utility loss of 18 utils.

In comparison, he experiences a gain of 27 from the two more movies, resulting in a net utility gain of 7.

In other words, José might feel happier with the two movies instead of the fourth T-shirt.

Thus, the total profit or loss for the color of the T-shirt that was given up would be calculated based on the difference in utility gained from the two cases.
