Respuesta :
50 km/h = 4 hours
60 km/h = x hours
50x = 60×4
50x = 240
x = 4.8 hours
60 km/h = x hours
50x = 60×4
50x = 240
x = 4.8 hours
3 hours and 20 minutes
Step-by-step explanation:
If you are going 50km/h for 4 hours then you travel a total of 200km so now you multiply 60 by 3 to get a total of 180km then subtract 180km from 200km to see what is missing then you get 20km and since you are going 60km/h and 20km are missing every km is a minute long so it would be 3 hours and 20 minutes.
