Gina rides her bike to work at an average of 10.4 miles per hour. She bikes 1.2 hours each day. How many miles does Gina ride ea
tatiyna
So 10.4mi = 1 hour

We need to find out how many miles 1.2 hours is.

1.) Well, the first step would be to multiply 1.2 on both sides of:
10.4mi = 1 hour

because that would make this number of miles is = to 1.2 hours which is wha we're looking for

1.2(10.4) mi = 1.2 hour

2.) Simplify
12.48 mi = 1.2 hour

3.) That means Gina rides 12.48 miles each day if she rides for 1.2 hours each day at a pace of 10.4 miles per hour :)

I need to drink 8 2/4 cups of water and 2 1/5 cups milk every day. How much fluid do I have to drink?
lidiya [134]

Answer:

The total fluid you have to drink is 10  7/10  =  10.7  cups.

Step-by-step explanation:

The daily requirement  of water =  8 2/4 cups

Now, 8 \frac{2}{4}  = 8+  \frac{2}{4}  = 8+ 0.5 = 8.5

or, the daily water requirement = 8.5 cups

The daily requirement  of milk =  2 1/5 cups

Now, 2 \frac{1}{5}  = 2+  \frac{1}{5}  = 2+ 0.2 = 2.2

or, the daily milk requirement = 2.2 cups

So, The total fluid needed  = Cups of  (Water + Milk) needed

                                              =  8.5 cups + 2.2 cups

                                              = 10.7 cups

Also, 10.7 = 10 + 0.7 = 10 + \frac{7}{10}  = 10\frac{7}{10}

Hence, the total fluid you have to drink is 10 7/10 cups.

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.
