if you have drived in 2 hours and 50min and you have drived 60km what is youre medium driving speed?

2 hours + 50/60 =2 5/6 hours =17/6 hours.

60 / (17/6) = 60 x 6/17 =360/17 =21 3/17 km/h - the average speed.

2 hrs 50 min   =   2 + 5/6 hrs  =  17 / 6 hrs

So

D / T   = R

60 km / [17/6] hrs  =

60 * 6 / 17  km/hr   ≈  21.18 km / hr

if you have drived in 2 hours and 50min and you have drived 60km what is youre medium driving speed?

\(\large v=\frac{s}{t}=\frac{60km}{(2+\frac{50}{60})h}=\frac{60km}{2.83\overline3h}=\color{blue}21.176\ km/h\)
