Question

Wafa runs 8 kilometers in 60 minutes. At this rate, how long would it take her to run 2 kilometers?

Answer 1

Time = 0.25 hours

Step-by-step explanation:

He runs,

8 km ⇒ 60 minutes

Now let's find the speed he runs

We know that, (60 min = 1 hour)

`speed = (distance)/(time) \\speed= (8 km)/(1h)\\speed = 8kmh^(-1)`

At the same speed, now let's find the time which takes to run 2 km

`speed = (distance)/(time)\\Time = (distance)/(speed) \\Time = (2 km)/(8 km/h) \\`

`Time = 0.25 h`

Answer 2

• Distance=8km
• Time=60min=1h

`\\ \bull\tt\longmapsto Speed=(Distance)/(Time)`

`\\ \bull\tt\longmapsto Speed=dfrac{8}{1}`

`\\ \bull\tt\longmapsto Speed=8km/h`

Now

• Distance=2km

`\\ \bull\tt\longmapsto Time=(Distance)/(Speed)`

`\\ \bull\tt\longmapsto Time=(2)/(8)`

`\\ \bull\tt\longmapsto Time=0.25h`
