Answer:

John needs $3\frac{3}{4}$ yards of blue ribbon.

Step-by-step explanation:

We have been given that Jon uses a piece of red ribbon witch is 3/4th yard long. Jon also needs blue ribbon that is 5 times as long as the ribbon. We are asked to find the amount of blue ribbon that John needs.

To find the amount of blue ribbon that John needs, we will multiply amount of red ribbon by 5 as shown below:

$\text{Amount of blue ribbon}=5\times \frac{3}{4}$

$\text{Amount of blue ribbon}=\frac{5\times 3}{4}$

$\text{Amount of blue ribbon}=\frac{15}{4}$

$\text{Amount of blue ribbon}=3\frac{3}{4}$

Therefore, John needs $3\frac{3}{4}$ yards of blue ribbon.

Answer:

85 km/h

Step-by-step explanation:

Let s represent the speed of the slower car. Then the travel time is ...

time = distance/speed

2 = 360/(s +(s+10))

4s +20 = 360 . . . . . multiply by 2s+10

4s = 340 . . . . . . . . . subtract 20

s = 85 . . . . . . . . . . . divide by 4

The rate of the slower car is 85 km/h.
