Y= 4/10x describes the number of kilometers y that a van travels in x minutes. What is the constant speed of the van in terms of hours?express the speed in 3 different ways
The constant speed of the van can be expressed in terms of hours by converting the time from minutes to hours. Since there are 60 minutes in an hour, we can divide x by 60 to convert it to hours.
1. y = (4/10)x km
Speed in terms of hours: (4/10)(x/60) km/h
Simplified speed: (2/5)(x/60) km/h
2. y = (4/10)x km
Speed in terms of hours: (4/10)(1/60)x km/h
Simplified speed: (2/300)x km/h
3. y = (4/10)x km
Speed in terms of hours: (4/600)x km/h
Simplified speed: (2/300)x km/h
