Question

A car travels 500 m in 50 s, then 1500 m in 75 s. Calculate its average speed

for the whole journey.​

Answer 1

To calculate the average speed for the whole journey, we can divide the total distance traveled by the total time taken. The car travels 500 meters in 50 seconds, giving us a speed of 10 meters per second. Then, it travels 1500 meters in 75 seconds, giving us a speed of 20 meters per second. Adding up the total distance (500 + 1500 = 2000 meters) and the total time (50 + 75 = 125 seconds), we can find the average speed by dividing the total distance by the total time. Therefore, the average speed for the whole journey is 2000 meters divided by 125 seconds, which equals [16 meters per second.]

Answer 2

To calculate the average speed for the whole journey, we need to find the total distance traveled and the total time taken.

First, let's find the total distance traveled. The car traveled 500 m in 50 s and then 1500 m in 75 s. So, the total distance traveled is 500 m + 1500 m = 2000 m.

Next, let's find the total time taken. The car took 50 s to travel the first distance and 75 s to travel the second distance. So, the total time taken is 50 s + 75 s = 125 s.

To find the average speed, we divide the total distance traveled by the total time taken. In this case, the average speed is 2000 m / 125 s = 16 m/s.

Therefore, the average speed for the whole journey is 16 m/s.
