Bunuel how did you calculate time ?
1/12 ...does it means that it takes 5 minutes for every 12 miles ?
5 minutes is 1/12 hour.
hi
Bunuel, if i change 5 minutes into 10 minutes interval.
so:
first interval the speed id 20 km per hour
second interval is 30 km per hour
third interval is 40 km per hour
Speed = \(\frac{40 km (distance)}{60 minutes (time)}\)
Time in 10-minute interval, means what distance did the car in 10 minute interval at a speed of 40 km per hour.
Time = \(\frac{distance}{speed}\)
Distance = \(speed * time\) ---> \(\frac{40 km (distance)}{60 minutes (time)}\) * 10 = 6,7 miles
Is my understanding correct ?
thank you
