If you travel at an average speed of 45 mi/hr and home is 6.1 km away, how long will it take you to get home? 1 km = 6.21 mi

Question

Just want to know how to set this up

Answer 1

According to question, 1km = 6.21 mi

Distance to home = 6.1 km = 6.1 * 6.21 mi = 37.881 mi

 

Speed = 45mi/hr

 

Time = Disctance/speed

        = 37.881/45

        = .84 hr = 50.5 minutes

Answer 2

6.1(6.21) = 37.881 miles

 

37.881/45 = 0.8418

 

0.8418(60) = 50.508

 

It should take 50 minutes and 31 seconds to get home.
