    Counting Time
Click For Summary
SUMMARY

The discussion centers on calculating time based on distance and speed using the formula t = s/v, where t represents time, s is distance, and v is speed. A user inquires about determining the time taken to travel 45 kilometers at a speed of 100 kilometers per hour. The calculation yields 0.45 hours, which converts to 27 minutes, confirming that the travel time is indeed 27 minutes for the given distance and speed.

PREREQUISITES
  • Understanding of basic physics concepts such as speed, distance, and time.
  • Familiarity with the formula t = s/v for calculating time.
  • Basic arithmetic skills for unit conversion.
  • Knowledge of converting hours to minutes (1 hour = 60 minutes).
NEXT STEPS
  • Study the relationship between speed, distance, and time in physics.
  • Practice additional problems using the formula t = s/v with varying distances and speeds.
  • Learn about unit conversions, specifically converting hours to minutes and vice versa.
  • Explore real-world applications of speed, distance, and time calculations in transportation and logistics.
USEFUL FOR

This discussion is beneficial for students learning physics, individuals preparing for driving tests, and anyone interested in understanding basic calculations related to speed and travel time.

I have very disappointed myself. I am forgot how count time, if car drives example 45 km(kilometre) distance and it's speed is 100km/h ( kilometre per hour). How i know what is time?

equation is

t = s/v (t = time, s = distance and v = speed)

and now equation is

t = 45km / 100km/h
t = 0,45h?

How i know this (0,45h) what is exactly time? Can somebody count this for me?

Do you mean convert this to minutes?

You have 0.45h, there are 60 minutes to an hour, so 60 * 0.45 = 27minutes.
 
I don't understand your problem. Yes it would take .45 hr or .45hr * 60min/hr = 27min to travel 45km at 100km/h.
