If it takes B hours to walk a certain distance at the rate of 3 miles per hour, the number of hours it takes to return the same distance at 4 miles per hour is...?
4/3 the speed means 3/4 the time.
time = distance/speed
whats the answer then...?
To find the number of hours it takes to walk the same distance at a different rate, you can use the formula:
Time = Distance / Speed
In this case, the distance remains the same, so we can write:
Time1 = Distance / Speed1
Where Time1 represents the time it takes to walk the distance at the initial speed of 3 miles per hour.
Now, we can substitute the given values:
Time1 = Distance / 3
Similarly, to find the number of hours it takes to walk the same distance at a speed of 4 miles per hour, we can write:
Time2 = Distance / Speed2
Where Time2 represents the time it takes to walk the distance at the new speed of 4 miles per hour.
Substituting the values:
Time2 = Distance / 4
Since both Time1 and Time2 represent the time it takes to walk the same distance, we can set them equal to each other:
Distance / 3 = Distance / 4
Now, solving for Distance, we can cross-multiply:
4 * Distance = 3 * Distance
This results in:
4 Distance = 3 Distance
To find the number of hours it takes to return the same distance at 4 miles per hour, we need to determine the value of Distance. However, the information provided in the question does not give us enough information to calculate a specific value for Distance. Therefore, we cannot determine the exact number of hours it takes to walk back at 4 miles per hour.
