Thank you for asking this question. This a really interesting but an easy question.
We have to calculate the average speed so we just have to add all the distances and all the time taken and finally divide the two as speed is equal to distance / time.
So distance = 45 + 7.5 + 87.5. Time = 45 + 15 + 75 so 140/2.25 is the answer.
I hope this answer can help you in some manner.
