<h2>Answer:</h2>

<u>She rode for </u><u>2.5 hours</u>

<h2>Step-by-step explanation:</h2>

The formula for speed is

Speed = Distance / time

so arranging the equation for time

Time = Distance / Speed

Time = 17.5 / 7

Time = 2.5 hours

Answer:

2.5 hours

Step-by-step explanation:

To calculate the time taken to travel the distance, we will apply the distance speed time formula, which links the speed of an object, the distance traveled by it and the time taken for it to travel the distance as follows:

Time taken to travel the distance = Distance Traveled / Average Speed

We know the average speed to be 7 km/h

and the total distance traveled to be 17.5 km

Using these values and putting them in the equation we get,

Time taken = 17.5 / 7 = 2.5
