Answer:

63 m

Step-by-step explanation:

We know the rate in 45 m / min

We need to change the time to min

1 min 24 sec

We know that 1 min = 60 sec  so 24 seconds is 24/60 ths of a minute

1 min 24/60 min

1 2/5 min

Changing to decimal form

1.4 minutes

Now we multiply by the rate to get the distance

d = r *t

d = 45 m/ min * 1.4 min

d= 63 m

Answer:

I would first divide 45 meters by 60 seconds to know now far Alex swims every second:

45/60 = .75m/second.

Then I would multiply .75×24 seconds:

.75 ×24 = 18 meters in 24 seconds.

Add the 45 meters he swam in one minute to the 18 meters he swam in 24 seconds.

He swam 63 meters in 1 minute 24 seconds.

Answer:

6 x (-4)

when multiplying integers, you first need to multiply the numbers. Then you need to look at the signs if both numbers have the same signs or if it doesn't. if the signs are the same, the product is a positive . If the two numbers have different signs, you will get a negative product.

NOTE: if a number doesn't have a sign, it's a positive number
