Answer:

43

Step-by-step explanation:

Given data:

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
