Distance
= Speed x Time
= 90m/min x 7min
=630m
Speed (For Alfamart back to home)
= Distance / Time
= 630m / 8min
= 78.75m/min
However if it is for the entire trip,
Average Speed
= Total Distance / Total Time
= 1260m / 15min
= 84m/min
So, is the question wrong?
you can double-check with the source of this question 🙂
