Question
A car travelled from A to B and then continued to C.It travelled from A to B at an average speed of 30 km/h.The distance from A to B is 90 km.(a) How many hours did the journey from A to B take?(b) The distance from B to C is 50 km and took 1 hour.
Solution
(a) To find the time it took for the car to travel from A to B, we can use the formula: time = distance / speed. Given that the distance from A to B is 90 km and the average speed is 30 km/h, we can substitute these values into the formula: time = 90 km / 30 km/h. Simplifying this equation, we get: time = 3 hours. Therefore, the journey from A to B took 3 hours.
(b) The distance from B to C is given as 50 km and it took 1 hour to travel this distance. Therefore, the average speed for this part of the journey can be calculated using the formula: speed = distance / time. Substituting the values, we get: speed = 50 km / 1 hour. Simplifying this equation, we find that the average speed from B to C is 50 km/h.
