Answer: 6,320 metres
Explanation:
The first ratio is 3 km:45 minutes, divide both sides by 3, and from this we can tell that Ruchi can cover 1 km in 15 minutes. Next, we want to know: 15 minutes times what number is 94.8? So, we divide 94.8 by 15 to get 6.32 as our multiplier.
We also know that 1km = 1,000 m. So, we multiply 1,000 by 6.32 to get 6,320 m.
Therefore, Ruchi covers 6,320 metres in 94.8 minutes.
