Question

Anne travels for 1.5 hours at an average speed of 40km/h
how far does she travel

Answer 1

Hello!

1. Formula

distance = speed * time

2. Application

distance

= 40km/h * 1.5h

= 60km

3. Conclusion

She travel 60km.

Answer 2

60 km

Explanation:

In order to find the distance that Anna has travelled, we can derive the formula from the speed formula which is:

`\displaystyle{v=(s)/(t)}`

where v is speed, s is distance and t is time. So by solving for distance (s), we have:

`\displaystyle{s=vt}`

Apply the distance travelled formula, we know that speed (v) = 40 km/h and time (t) = 1.5 hours. Thus,

`\displaystyle{s=40 \ \text{km/h} \cdot 1.5 \text{h}}\\\\\displaystyle{s=60\ \text{km}}`

Therefore, Anna travels 60 kilometers.
