Answer: 9.5 laps (9.5 voltas)
Explanation:
A rough translation of this is:
"In a race, the speed of the bikers is 16km/h. Assuming that the training lasts 50min, and the length of the track is 1400mts, how many laps did the bikers?"
First, remember the relation:
Distance = Speed*time.
In this case:
Speed = 16km/h
time = 50min
We have two different units for time, hours and minutes.
We know that 1 hour = 60 minutes.
Then we can write the speed as:
Speed = 16km/(60min) = 0.267km/min
And for the distance we alsohave two units, the lenght of the track is in meters, and the speed is in Km, knowing that:
1km = 1000m
We can write the distance of the track as:
1400m = (1400/1000)km = 1.4km
Now, all the data that we have is:
Speed = 0.267 km/min
Time = 50 min
Length of the track: 1.4km.
and using the relation: Distance = Speed*time.
we can find the total distance traveled by the bikers:
Distance = 0.267km/min*50min = 13.33km
Now, if each lap is 1.4km long, then in 13.33km the bikers did:
13.33km/1.4km = 9.5 laps.
