Answer:
(15 + f) feets
Step-by-step explanation:
Given that:
Race between Jay and Pete:
Let ;
distance covered by Jay = j
Distance covered by Pete = p
At 9:00a.m :
Jay was 15 feet ahead of Pete
Hence,
j - p = 15 feet
At 10 a.m :
Pete was 'f' feet ahead of Jay:
p - j= f feets
Number of feets Pete ran than Jay between 9 to 10 a. M
f feets + number of feets at which Pete was being Jay at 9a.m
f feets + 15 feets = (15 + f) feets
