Omar begins training for a 5 km race by running 0.75 km the first day, 0.85 km the second day, and 0.95 km the third day. If he keeps increasing his distance each day according to the pace of his first three days, what is the first day in his training program that Omar will run greater than 5 km?

43

Step-by-step explanation:

Given dа ta:

1st day he ran 0.75 km

2nd day he ran 0.85 km that is an increase of 0.1 km

3rd day he ran 0.95 that is an increase of 0.1 km

let the number of days be x where x starts from 0

0.75 + 0.1 x = 5

0.1 x = 5-0.75 Solving for x

0.1 x = 4.25 Dividing both sides by 0.1

x = 42.5

Omar will run 5 km on the 42.5 day meaning Omar will run greater than 5 km on the 43rd day
