A boy walks 13 km in 2.0 h. What is his speed in km/h and m/s. Show work.
If you want it in km/h, divide 13 km by 2 h.
If you want it in m/s, multiply the km/h value by (1000 m/km)x(1 h/3600s)
Well, well, well, a walking boy with a need for speed! Let's crunch some numbers, shall we?
To find the speed, we simply divide the distance traveled (13 km) by the time taken (2.0 hours).
Speed (km/h) = Distance ÷ Time
Speed (km/h) = 13 km ÷ 2.0 h
Speed (km/h) = 6.5 km/h
Voila! The boy's speed is 6.5 km/h.
Now, if you'd like to convert this speed into m/s, we'll need a little bit more clown magic. Since 1 km = 1000 m and 1 hour = 3600 seconds, we can use these conversion factors to go from km/h to m/s.
Speed (m/s) = Speed (km/h) × (1000 m / 1 km) ÷ (3600 s / 1 h)
Speed (m/s) = 6.5 km/h × (1000 m / 1 km) ÷ (3600 s / 1 h)
Speed (m/s) ≈ 1.81 m/s
Ta-da! The boy's speed is approximately 1.81 m/s.
So now you have his speed both in km/h and m/s. Happy walking!
To find the boy's speed in km/h, we can use the formula:
Speed (km/h) = Distance (km) / Time (h)
Given that the boy walks a distance of 13 km in a time of 2.0 hours, we can substitute the values into the formula:
Speed (km/h) = 13 km / 2.0 h = 6.5 km/h
Therefore, the boy's speed is 6.5 km/h.
To convert km/h to m/s, we can use the conversion factor:
1 km/h = 0.2778 m/s
Using this conversion factor, we can convert the boy's speed from km/h to m/s:
Speed (m/s) = 6.5 km/h x 0.2778 m/s = 1.8055 m/s
Therefore, the boy's speed is 1.8055 m/s.
To find the boy's speed, we need to divide the distance he walked by the time taken.
To find the boy's speed in km/h:
Speed (km/h) = Distance (km) ÷ Time (h)
Given: Distance = 13 km and Time = 2.0 h
Speed (km/h) = 13 km ÷ 2.0 h
To divide 13 km by 2.0 h, simply perform the division:
Speed (km/h) = 6.5 km/h
So, the boy's speed is 6.5 km/h.
To convert the boy's speed from km/h to m/s, we need to use the conversion factor: 1 km/h = 0.2778 m/s.
Speed (m/s) = Speed (km/h) × Conversion factor
Given: Speed (km/h) = 6.5 km/h
Speed (m/s) = 6.5 km/h × 0.2778 m/s
To calculate, multiply 6.5 km/h by 0.2778 m/s:
Speed (m/s) ≈ 1.805 m/s
Therefore, the boy's speed is approximately 1.805 m/s.
