Question

How many minutes will it take for a car traveling 74 miles per hour to cover 6.50 kilometers?

Answer 1

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
