Kendall rows at a steady pace of 500 meters per minute. Before she started her timed session, she had already rowed 1,200 meters to warm up. If her total distance for the day was 4,700 meters, how many minutes did her timed session last?
Let m = minutes
500m + 1200 = 4700
m = 6
Her timed session was 6 minutes.
Solve for x.
6 + 3x - 5x = 4
x =1
