Answer: 0.395 km

Step-by-step explanation:

Let Martin distance from the hole be X

On first stroke, his golf ball traveled 4/5 of the distance to the hole. That is 4/5 X

On his second stroke, the ball traveled 79 meters and went into the hole

Total distance covered will be

X = 79 + 4/5X

X - 4/5X = 79

X - 0.8X = 79

0.2X = 79

X = 79/0.2 = 395 meters

How many kilometers from the hole was Martin when he started

X = 395/1000 = 0.395 km
