Question

A car travels at a speed of 60 km/h for 1 h and at 30 km/h for the next 2 h. Calculate the average speed of the car.

Answer 1

Answer:

40 kmph

Explanation:

Average speed = Total distance covered / total time taken

total distance = (60 * 1)  + (30 * 2)

Total distance = 120 km

Total time = 1 hr + 2 hr = 3 hr

Average speed = 120 / 3 kmph = 40 kmph

Answer 2

Answer:

average is equals to to total distance upon total time taken so total distance is equals to 60 + 30 kilometre per hour upon 2 hour plus one hour is equals to 90 km per hour upon 3 hours now change 90 km into into metre and 3 hour seconds so 90 km is equals to 9000 m and 3 h is equals to to 10800 s so the answer is 8.3m/s I hope it is right answer like it and Mark it brainliest
