There are 1.609344 kilometres in one mile. Therefore, rounded to two decimal places, 320 kilometres is equal to 320/1.609344 = 198.84 miles.5 mi * 1.609 km/1mi = 88.49 km    55 mi/hr = 88.49 km/hr    The formula to convert miles to km    55 mi    *      63360 in   1 mi    â¦   *      2.54 cm   1 in      *      1 km   100000 cm      =    88.51392 km  /  . 18 people found this useful.
So in the case of this problem we have an average velocity of $\,0\,\,mph$ and an average speed of ${{120miles + 120miles} \over {{{120miles} \over {40mph}} + {{120miles} \over {60mph}}}}\,\,\,mph$ which equals $\,48\,\,mph$ .0 miles per hour is 1 minute per mile, while 40 miles per hour is 1.5 minutes per mile. Since we travel the same number of miles at each speed, we can now take the mean of these two figures. That's 1.25 minutes per mile on average. For 240 miles total, 240miles*1.25minutes/mile = 300 minutes = 5 hours.
