What is trực tiếp bóng đá k+ formula for calculating distance IN vIETNAM?
trực tiếp bóng đá k+ formula for calculating distance is:
S = v × t
*Where:
S: Distance traveled (usually measured in meters, kilometers)
v: Speed (usually measured in meters/second, kilometers/hour)
t: Travel time (usually measured in seconds, hours)
*Example:
A car travels at a speed of 50 km/h for 2 hours. trực tiếp bóng đá k+ distance trực tiếp bóng đá k+ car travels is: S = v × t = 50 km/h × 2 h = 100 km
From trực tiếp bóng đá k+ above formula, we can derive formulas to calculate speed and time:
To calculate speed: v = S / t
To calculate time: t = S / v
Example 1: Motorcycle on a highway
Problem: A motorcycle travels on a highway at a speed of 80 km/h for 3 hours. Calculate trực tiếp bóng đá k+ distance traveled by trực tiếp bóng đá k+ motorcycle.
Solution:
Using trực tiếp bóng đá k+ formula: S = v × t
Substitute numbers: S = 80 km/h × 3 h = 240 km
Result: trực tiếp bóng đá k+ motorcycle travels a distance of 240 km.
Example 2: Pedestrian
Problem: A person walks at a speed of 5 km/h for 30 minutes. Calculate trực tiếp bóng đá k+ distance traveled by trực tiếp bóng đá k+ person.
Solution:
Convert 30 minutes to 0.5 hours (since speed is measured in hours)
Using trực tiếp bóng đá k+ formula: S = v × t
Substitute numbers: S = 5 km/h × 0.5 h = 2.5 km
Result: trực tiếp bóng đá k+ person travels a distance of 2.5 km.
Example 3: Calculating travel time
Problem: A train runs at a speed of 60 km/h. How much time is needed to cover trực tiếp bóng đá k+ distance of 180 km?
Solution:
Using trực tiếp bóng đá k+ formula: t = S / v
Substitute numbers: t = 180 km / 60 km/h = 3 hours
Result: trực tiếp bóng đá k+ train needs 3 hours to cover trực tiếp bóng đá k+ distance of 180 km.
Example 4: Calculating speed
Problem: A bicycle travels a distance of 15 km in 1.5 hours. Calculate trực tiếp bóng đá k+ speed of trực tiếp bóng đá k+ bicycle.
Solution:
Using trực tiếp bóng đá k+ formula: v = S / t
Substitute numbers: v = 15 km / 1.5 h = 10 km/h
Result: trực tiếp bóng đá k+ speed of trực tiếp bóng đá k+ bicycle is 10 km/h.
