Jack jogs for 30 minutes and he rides his bike for 45 minutes
Let x represent the number of minutes jogged and y represent the number of minutes that he ride his bike.
Jack jogs and rides his bike for a total of 75 minutes every day. hence:
x + y = 75 (1)
He rides his bike for 15 minutes longer than he jogs. hence:
y = x + 15
-x + y = 15 (2)
Solving equations 1 and 2 simultaneously gives:
x = 30, y = 45
