On Martin’s first stroke his golf ball traveled 4/5 of a distance to the hole. On his second stroke the ball landed 79 m and went into the hole. How many kilometers from the hole was Martin when he started?

 0.395 Km from the hole was Martin when he started.

Step-by-step explanation:

Let be K the distance to the hole when Martin started

We are told that first the ball traveled 4/5 of K

Then the ball has yet to go:

K - 4K/5 = (5K - 4K)/5 = K/5

We are told that K/5 = 79m

Then K = 5*79m = 395m

We know 1Km = 1,000m

Then 395m*1km➗1,000m = 0.395 Km

0.395 Km from the hole was Martin when he started.
