Question

A train travels $120 \text{ km}$ in $2 \text{ hours}$. What is its speed?

• A. $40 \text{ km/h}$
• B. $50 \text{ km/h}$
• C. $60 \text{ km/h}$
• D. $80 \text{ km/h}$

Hint:

Ensure units are correct. If the distance unit is kilometer ($\text{km}$) and time unit is hour ($\text{h}$), the resulting speed is in $\text{km/h}$.

Answer 1

The Correct Option is C

Speed is calculated by dividing distance by time.
$\text{Speed} = \frac{\text{Distance}}{\text{Time}}$.
Given: $\text{Distance} = 120 \text{ km}$.
Given: $\text{Time} = 2 \text{ hours}$.
$\text{Speed} = \frac{120 \text{ km}}{2 \text{ hours}}$.
$\text{Speed} = 60 \text{ km/h}$.
