Fun. It took Joelle 1/4 hour to get there. It took Andrea 1/2 hour and Kellan 3/4 hours.
Their distances are simply rate times time,
j = 35(1/4) = 35/4 = 8.75 miles
a = 3(1/2) = 1.5 miles
k = 14(3/4) = 21/2 = 10.5 miles
Answer: 10.5 miles
Next part. It took Kellan 12/15=4/5 hour to bike to Andrea.
Let's assume it's the same restaurant. They had to walk 1.5 miles, which they did at 2.5 mph, 1.5/2.5=3/5 hours.
So Keelan traveled for 4/5+3/5=7/5 hours, which is 1 hour, 24 minutes.
They got there 5 minutes early, 8:55, so Keelan left at 7:31 am
Answer: 7:31
