Sagot :
Two locomotives with a speed of 150 km/h each, reach the other in: 1.9 min
The formula of reach time and procedure we will use to solve this problem is:
Tr = x/(v2+v1)
Where:
- Tr = reach time
- x = separation distance
- v2 = velocity of the faster mobile
- v1 = velocity of the slowest mobile
Information about the problem:
- x = 9.5 km
- v2 = 150 km/h
- v1 = 150 km/h
- Tr=?
Applying the reach time formula we get:
Tr = x/(v2+v1)
Tr = 9.5 km/(150 km/h + 150 km/h)
Tr = 9.5 km/(300 km/h)
Tr = 0.032 h
By converting the time units from (h) to (min) we have:
0.032 h * (60 min / 1h) = 1.9 min
What is velocity?
It is a physical quantity that indicates the displacement of a mobile per unit of time, it is expressed in units of distance per time, for example (miles/h, km/h).
