To answer this question we need to first convert 1 km in miles and then 4 minutes into hours.
First 1 mile = 1.6 km
So 1 km / 1.6 = 0.625 miles (approximately)
Now 60 minutes = 1 hour
So 4/60 = 1/15 of an hour
Since speed = distance/time we have
Speed = 0.625/1/15 = 9.375 miles per hour.

6.5/4 = 1.625 h 1.625 x 60 = 97.5 minutes 6.5 miles at 4 MPH will take you 97.5 minutes, or one hour and 37.5 minutes
70 minutes = 70/60 hr = 7/6 of an hour. So Miles/hour = (4 miles)/(7/6 hour) = 24/7 MPH which is about 3.43 MPH.
