The truck is moving at a speed of 80 km / h. a passenger car is moving towards him at a speed of 100 km / h. What is the speed of a car relative to the speed of a truck.
v1 = 80 km / h – truck speed;
v2 = 100 km / h – car speed.
It is required to find v – the speed of a car relative to a truck.
Since cars are moving towards each other, the speed of a car relative to a truck is determined as the sum of the speeds of both cars:
v = v1 + v2 = 80 + 100 = 180 km / h.
Answer: the speed of a car relative to a truck is 180 km / h.
