Answer:

Calculate the average speed, in km/h, for a journey of distance 270 km in time 4 h

Step-by-step explanation:

speed = Distance/time

Speed = 270/(2 hrs + 10 mins) = 270/(2+{10÷60})

Speed = 270/(2+1/6) = 270/(13/6) = (270×6)÷13

Speed = 1620 ÷13 = 124.62km/hr ~ 100km/hr

At 100km/h you travel 2*100+(10/60)*100 km around 216.66666666667 km in two hours and ten minutes.

Edit. If you want to travel 270 km in two hours and ten minutes you have to go at 124.62 km/h. (270/(2+10/60)
