How do you Convert 50 meters to per second to km/h ? Btw i need to know how to solve it

erma4kov [3.2K]

50 m/s is going to be 180 km/h or 3 km/s.

50 / 1000 = 0.05

0.05 x 60 = 3 kilometers a minute.

3 x 60 = 180 kilometers an hour.

50 m/s divided by 1 kilometer = 0.05 kilometers a second. You then multiply it by 60 to get it in minutes, and then 60 again to get it in hours. because their are 3600 seconds in an hour. So you could divide 50 meters per second by 1000 meters or 1 kilometer and then multiply it by 3600 seconds to get 180 kilometers an hour.

Nesterboy [21]

Answer:

20,309 people more people per sq mile.

Step-by-step explanation:

First step is to calculate the population density of both cities, then we'll be able to answer the question.

We're looking for a number of people per sq mile... so we'll divide the population by the area.

New York City: 8.54 million people on 302.6 sq miles

DensityNYC = 8,540,000 / 302.6 = 28,222 persons/sq mile

Los Angeles: 3.98 million people on 503 sq miles

DensityLA = 3,980,000 / 503 = 7,913 persons/sq mile

Then we do the difference... 28,222 - 7,913 = 20,309 people more people per sq mile.

If we were to make the ratio, we'd get 3.57, 3.57 more people in NYC per sq mile compare to LA.
