Hezekiel runs 1000 m at a rateof 3 minutes per km. how long does he take to run 500 m​
lana66690 [7]

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.

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.
