Question

Samin can run 5 kilometers in 30 minutes. Assuming she keeps a constant pace, how many kilometers can she run in 45 minutes

Answer 1

Answer:

7.5 kilometres

Step-by-step explanation:

In 30 minutes she ran 5 kilometres.

We know that 30 + 15 = 45, so we can divide the minutes and kilometres by 2.

So 30 divided by 2= 15 minutes.

And 5 kilometres divided by 2= 2.5 kilometres.

Now we just add the two distances, as we know that the minutes make 45.

2.5 + 5 = 7.5.

I hope this helps, have a lovely day.

Answer 2

The speed is the distance covered by an object at a particular time. The distance covered by Saima in 45 minutes is 7.5 km.

What is speed?

The speed is the distance covered by an object at a particular time. Therefore, it is the ratio of distance and time.

$\rm{Speed = \dfrac{Distance}{Time}$

Given Samin can run 5 kilometres in 30 minutes. Therefore, the speed of Samin will be,

Speed = 5km/30min = 5/30 km per minute

The distance covered by Saima in 45 minutes will be equal to

Distance = 5/30 × 45 = 7.5 km

Hence, The distance covered by Saima in 45 minutes is 7.5 km.
