answer this please.
1.
Given:
- Distance \( d = 50 \) meters
- Time \( t = 60 \) seconds
Unknown:
- Speed
Formula:
\[ \text{Speed} = \frac{\text{Distance}}{\text{Time}} \]
Solution:
\[ \text{Speed} = \frac{50 \text{ meters}}{60 \text{ seconds}} \]
\[ \text{Speed} = \frac{50}{60} \text{ meters/second} \]
Final Answer:
\[ \text{Speed} = \frac{5}{6} \text{ meters/second} \]
2.
Given:
- Distance \( d = 100 \) kilometers
- Time \( t = 2 \) hours
Unknown:
- Speed
Formula:
\[ \text{Speed} = \frac{\text{Distance}}{\text{Time}} \]
Solution:
\[ \text{Speed} = \frac{100 \text{ kilometers}}{2 \text{ hours}} \]
\[ \text{Speed} = \frac{100}{2} \text{ kilometers/hour} \]
Final Answer:
\[ \text{Speed} = 50 \text{ kilometers/hour} \]
3.
Given:
- Distance \( d = 450 \) kilometers
- Time \( t = 1.5 \) hours
Unknown:
- Velocity
Formula:
\[ \text{Velocity} = \frac{\text{Distance}}{\text{Time}} \]
Solution:
\[ \text{Velocity} = \frac{450 \text{ kilometers}}{1.5 \text{ hours}} \]
\[ \text{Velocity} = \frac{450}{1.5} \text{ kilometers/hour} \]
Final Answer:
\[ \text{Velocity} = 300 \text{ kilometers/hour} \]
