Answer:
456.143684211 seconds
564.3 m
Explanation:
s = Distance
v = Velocity
Time is given by
Difference in time = 866.67-410.526315789 = 456.143684211 seconds
According to the question
The students would have to walk 564.3 m
The time elapsed when the vehicles are closest to each other is 20 min.
The given parameters:
- Speed of the truck, u = 80 km/h
- Distance, d = 32 km
- Speed of the car, v = 50 km/h
The time elapsed when the cars are close to each other is calculated by applying the principles of relative speed.
Thus, the time elapsed when the vehicles are closest to each other is 20 min.
