To express the ratio of Roger Bannister's distance to time in the unit indicated, we can set it up as follows:
- Distance: 5,280 feet
- Time: 4 minutes
The ratio of distance to time can be written as: \[ \text{Ratio} = \frac{\text{Distance}}{\text{Time}} = \frac{5,280 \text{ feet}}{4 \text{ minutes}} \]
Now, performing the division: \[ \text{Ratio} = 1,320 \text{ feet per minute} \]
So, the ratio of the two measurements is 1,320 feet per minute.
