In training for a swim meet, logan swam 750 meters in 1/3 of an hour. His swimming partner, Mila, swan 2/3 of logan’s distance in 1/4 of an hour. 1. What is logan’s average swimming speed?

2. What is Milas average swimming speed?

3. Compare Milas and Logan’s swimming speeds.

Step-by-step explanation:

typically speeds are measured in meters/second, kilometers/hour and such.

I guess, we need to go for "per hour" here.

Logan swam 750 meters in 1/3 hour.

what do we need to do to bring that ratio to a fraction that bases on 1 hour instead of 1/3 hour ?

right, we need to multiply to and bottom by 3.

750×3 / 1×3/3 meters/hour = 2250 / 1 meters/hour =

= 2250 meters/hour = 2.25 km/h

(by using 1000 meters = 1 kilometer).

so, logan's average swimming speed was 2.25 km/h

Mila swam 2/3 × 750 meters in 1/4 hour.

that is

2×750 / 3 meters in 1/4 hour.

1500 / 3 in 1/4 hour = 500 meters in 1/4 hour.

what do we need to do to bring this ratio to a fraction based on 1 hour ?

we need to multiply top and bottom by 4.

500×4 / 1×4/4 meters/hour = 2000 meters/hour = 2 km/h

Mila's average swimming speed was 2 km/h.

Logan was a little bit faster : 2.25 vs. 2 km/h

the correct answer is

c. 4

step-by-step explanation:

the given polynomial is

the degree of the polynomial is the highest exponent which is 4.

the -4 is called the leading coefficient.

this polynomial has only one term so it is a monomial.

the correct answer is option c.
