an automobile travels at a uniform speed of 88 kph. how many metres does it travel in 1 second?
a man walk 32.5m southward and 78m westward.if it took him 30 minutes to reach his destination.find his average speed?
88 km/h =88000/3600= 24.44 m/s
------
average SPEED = distance/time taken =(32.5+78)/30•60=0.062 m/s
displacement = sqrt(32.5²+78²)=84.5
average VELOCITY = displacement/time taken =84.5/30•60=0.047 m/s
To find out how many meters the automobile travels in 1 second, we need to convert its speed from kilometers per hour (kph) to meters per second (m/s).
1 kilometer is equal to 1000 meters, and 1 hour is equal to 3600 seconds.
So, let's convert the speed from kph to m/s:
Speed in kph = 88 kph
Speed in m/s = (88 kph) * (1000 m / 1 km) * (1 hour / 3600 seconds)
Simplifying the units:
Speed in m/s = (88 * 1000) / 3600
Speed in m/s = 88000 / 3600
Speed in m/s = 24.44 m/s (rounded to two decimal places)
Therefore, the automobile travels approximately 24.44 meters in 1 second.
To find out how many meters an automobile travels in 1 second, we need to convert the speed from kilometers per hour (kph) to meters per second (m/s). Here's how to do it:
Step 1: Convert 88 kilometers per hour (kph) to meters per second (m/s).
1 kilometer is equal to 1000 meters.
1 hour is equal to 3600 seconds.
To convert kph to m/s, we can use the following conversion factor: 1 kph = 1000 meters / 3600 seconds.
88 kph = (88 * 1000 meters) / 3600 seconds.
Step 2: Simplify the expression.
88 * 1000 meters = 88,000 meters.
Dividing 88,000 meters by 3600 seconds gives us the number of meters the automobile travels in 1 second.
88,000 meters / 3600 seconds = 24.44 meters per second (rounded to two decimal places).
Therefore, the automobile travels approximately 24.44 meters in 1 second when traveling at a uniform speed of 88 kph.
