Answer:

Yes

Step-by-step explanation:

To solve this problem, let's convert these into the same units.

We use the conversions:

- 1 hour = 60 min

- 1 min = 60 sec

- 1 mile = 5280 ft

40 miles/hour = 40 miles/60 minutes = \frac{40}{60} miles/min = \frac{40}{60} miles/60 seconds =

\frac{\frac{40}{60} }{60} miles/sec = \frac{\frac{40}{60} }{60}*5280 ft/sec = 176/3 ft/sec ≈ 58.67 ft/sec

Obviously, 58.67 ft/sec > 50 ft/sec.

Thus, yes, it is faster to drive a car going 40 mph than a car going 50 ft/sec.

Hope this helps!

Answer:

40 miles per hour is faster.

Step-by-step explanation:

First we have to find how many feet per hour the second car is going.

There are 60 seconds in a minute, and 60 minutes in an hour.

50*60=3600

There are 3600 seconds in a hour.

50*3600=180000

This means that the second car going 180000 feet per hour.

1 mile is 5280 feet.

Now we have to figure out how many miles 180000 is.

We can do that by setting up the following expression.

180000/5280=34 1/11 or 34.09

Since 40 is greater than 34.09, it is faster to drive a car going 40 miles per hour.

iren [92.7K]

Answer:

28.56

Step-by-step explanation:

First we need to calculate the mean average of the numbers

Average = 112+89+95+77+103/5

Average = 476/5

Average = 95.2

If Sam made 30% of goals in his last 6 games, then on average, amount made is expressed as;

Average of the last six games = 30% of 95.3

Average of the last six games  = 0.3 * 95.2

Average of the last six games = 28.56

Hence the required point average is 28.56
