Shelby leaves her house at 9:00am on her bike at a speed of 320 meters per minute. At 10:30 am, her brother, Colby leaves the house on his bike and tries to catch up with Shelby. Colby rides at a speed of 500 meters per minute. At what time will Colby catch up with Shelby?

Answer:

Step-by-step explanation:

320t=500(t-1.5)

320t=500t-750

-180t=-750

t=25/6

t=4+1/6 hours

So Colby catches up 4 1/6 hours after Shelby left. Since she left at 9am

9+4hours + 10 minutes. So they have travelled the same distance at 1:10pm
