Answer: 1 Minute & 30 Seconds

Step-by-step explanation: We can write a ratio to help determine the amount of time it will take for Ms. Bell and Olaiya to catch up to each other.

The ratio 20:60 shows that for every 20 miles Ms. Bell runs, Olaiya will run 60 miles per minute.

We can add up the total miles per minute they both run in the ratios below;

10:30 | 10 + 30 = 40 total miles in half a minute, 30 seconds

20:60 | 20 + 60 = 80 total miles in 1 minute

40:120 | 40 + 120 = 160 total miles in 2 minutes

The distance between Ms. Bell and Olaiya is 120 feet, which is a minute and half of a distance.
