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.
