Question

A bus travelling at 96 km/h completes a journey in 16 hours. At what speed will it have to cover the same distance in 8 hours?

• A. 192 km/h
• B. 188 km/h
• C. 193 km/h
• D. 197 km/h

Answer 1

Answer:

A. 192 km/h

Finding Distance

The equation for finding distance is:

$\text{Distance} = \text{Speed} \times \text{Time}$

Initial speed ($S_1$): $96 \text{ km/h}$

Initial time ($T_1$): $16 \text{ hours}$

$\text{Distance} (D) = 96 \text{ km/h} \times 16 \text{ h}$

Finding the New Speed

Find the speed ($S_2$) required to cover the same distance ($D = 1536 \text{ km}$) in 8 hours.

The equation for finding speed is:

$\text{Speed} = \frac{\text{Distance}}{\text{Time}}$

Distance ($D$): $1536 \text{ km}$

New Time ($T_2$): $8 \text{ hours}$

$\text{New Speed} (S_2) = \frac{1536 \text{ km}}{8 \text{ h}}$

$\text{New Speed} (S_2) = \mathbf{192 \text{ km/h}}$
