Question

an object moves through 10m in 2 minutes and next 10m in 3 minutes. calculate its average speed

Answer 1

Given that 1st object moves 10 meters in 2 minutes and the 2nd object moves 10 meters in 3 minutes

The formula for average speed is equal to total distance by total time

Now total distance is 10 + 10, that is 20 m

Total time is 2 + 3, that is 5 minutes, minutes has to be converted to seconds, that would be 5 x 60, equal to 300 second.

Now speed is 20 divided by time, 20 by 300, 0.066m/s

Answer 2

Answer:

4 m/min

Explanation:

t=2+3=5min

s=10+10=20

now

Vavg =toatal distance

_____________

total time

now

=20/5 = 4m/min
