Two trains are moving one after the other. The speed of the first is 98 km / h, the speed of the second is 76 km / h. Find the speed of the first relative to the second.
Given:
v1 = 98 kilometers / hour – the speed of the first train;
v2 = 76 kilometers / hour – the speed of the second train.
It is required to determine v (kilometer / hour) – the speed of the first train relative to the second.
According to the problem statement, both trains move in the same direction along one straight line. Then, to determine the relative speed, you need to use the following formula:
v = v1 – v2;
v = 98 – 76 = 22 kilometers / hour.
Answer: the first train moves relative to the second train at a speed equal to 22 kilometers per hour.
