Question

One morning mam cycled From her house to her Office at 5 km/he but owing to heavy traffic could return from her Office at 10 km/ hr what was the average speed for the two way trip

Answer 1

Answer:

7.5 km/h

Step-by-step explanation:

The question already gives you the two speeds at which the person traveled to her office. You need to find their average.

To find the average:

1) Add the numbers you want to find the average of.

2) Divide the sum by the amount of numbers you added together.

In this case, you would first add 5 and 10, to get 15. Since you added two numbers, to find their average, you would divide their sum (15) by two. 15 ÷ 2 = 7.5 (7 $\frac{1}{2}$)

Therefore, the answer to the question is 7.5 (7 $\frac{1}{2}$).

Answer 2

Answer:

(10 + 5)/2

=> 7.5 km/hr (answer)
