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 = [tex]\frac{40}{60}[/tex] miles/min = [tex]\frac{40}{60}[/tex] miles/60 seconds =
[tex]\frac{\frac{40}{60} }{60}[/tex] miles/sec = [tex]\frac{\frac{40}{60} }{60}*5280[/tex] 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.
