The empirical formula or simplest formula
gives the smallest whole-number ratio of
the atoms present in a compound.It gives the
relative number of atoms of each
element present in the compound.The ratio will be 3.72 : 21.28
Answer:
3.27 minutes
Explanation:
To solve this problem we will first convert miles/hour to km/min. For this purpose we will require following reference conversions as;
1 Mile = 1.60934 Km
And,
1 Hour = 60 min
Therefore,
As,
1 Mile = 1.60934 Km
Then,
74 Miles = X Km
Solving for X,
X = 74 miles × 1.60934 Km ÷ 1 mile
X = 119.10 Km
Therefore,
119.10 Km were travelled in = 60 min
So,
6.50 Km will be travelled in = X min
Solving for X,
X = 60 min × 6.50 Km ÷ 119.10 Km
X = 3.27 minutes
