What is the benchmark fraction of 7/10 x 16

Tomtit [17]

Lets change "16" by its to 16/1 .. since nothing can't help support 16 by itself when it is going into 7/10

Now that we change that ... your problem becomes 7/10 × 16/1

7/10 × 16/1 = 11 1/5

Because
7(16) / 10(1) = 112/10
Now lets go. to how we solve the for the answer

112/10 = 11 1/5

Taylor and Anya are friends who live 63 miles apart. Sometimes on a Saturday, they ride toward each other's houses on their bike

amid [387]

Answer:

Anya rode at 8.5 miles per hour.

Step-by-step explanation:

We have been given that Taylor and Anya live 63 miles apart. One day they left their houses at 8 am and met at 11 am riding toward each other. Taylor rode at 12.5 miles per hour.

We can see that Taylor and Anya met after 3 hours as 11-8=3. This means that both rode their cycles for 3 hours.

Let us find distance covered by Taylor.

$\text{Distance}=\text{Speed*Time}$

$\text{Distance covered by Taylor}=12.5\frac{\text{Miles}}{\text{hour}}*3\text{ hours}}$

$\text{Distance covered by Taylor}=12.5*3\text{ Miles}$

$\text{Distance covered by Taylor}=37.5\text{ Miles}$

Therefore, Taylor covered 37.5 miles in 3 hours.

Let us find distance covered by Anya in 3 hours by subtracting distance covered by Taylor from total distance of 63 miles.

$\text{Distance covered by Anya in 3 hours}=(63-37.5)\text{ Miles}$

$\text{Distance covered by Anya in 3 hours}=25.5\text{ Miles}$

Now let us find speed at which Anya rode bike.

$\text{Speed}=\frac{\text{Distance}}{\text{Time}}$

$\text{Speed at which Anya rode the bike}=\frac{25.5\text{ Miles}}{3\text{ Hour}}$

$\text{Speed at which Anya rode the bike}=8.5\frac{\text{ Miles}}{\text{ Hour}}$

Therefore, Anya rode the bike at the speed of 8.5 miles per hour.
