Step-by-step explanation:
1 km = 1000 m
(hence the term "kilo" which means 1000).
so. he runs 1000 m at the rate of 3 minutes per km, that means 3 minutes per 1000 m.
now, we can see the solution already with our eyes.
but let's do it formally :
the rate or ratio between time and distance must be the same for the same speed.
so,
3 min / 1000 m = x min / 500 m
500 m × 3 min / 1000 m = x min
1/2 × 3 min = x min
3/2 = 1.5 min = x min
so, it takes him 1.5 minutes (90 seconds) to run 500 m.

Answer:
790
Step-by-step explanation:
If 79 is 10% of his free throws than the full total is
79 times 10. 79 times 10 is 790.
Hope this helps :)

I would choose the answer b
1 day = 1500 bricks
5 days = 1500 x 5
5 days = 7500 bricks
Answer (a) He would expect to lay 7500 bricks in a five day week.
1500 bricks = 8 hours
1 brick = 8/1500
10 000 = 8/1500 x 10 000 = 53 hours (nearest hour)
Answer: (b) It will take him 53 hours to lay 10000 bricks.
