Answer:

It will 1.5 hours to Becky and Don to meet each.

Step-by-step explanation:

Let the time at which Becky and Don will meet be t.

Speed of Becky =60 mile/hr

Distance covered by Becky in t time ,x= 60miles/h \times t

Speed of Don = 80 mile/hr

Distance covered by Don in t time , y= 80miles/h \times t

Distance between both of them of 210 miles.

x+y=210 miles

60miles/h \times t+80miles/h \times t=210 miles

140 miles/h\times t=210 miles

t=\frac{210 miles}{140 miles}=1.5 hours

It will 1.5 hours to Becky and Don to meet each.

HELP PLEASEEE...Naming Your Solution When you are asked to name your solution if you have one... that means. When you have ONE s
Reptile [31]

Answer:

It means that you need to state whether there are any solutions and how many there are. For example if the equation ends up with an answer like 2=5 there is no solution because 2 does not equal 5. if the equation ends up with an answer of 0=0 there is infinitely many solutions because 0 does equal 0. if it comes out as x=9 there is one solution because x only has one answer to (keep in mind these are just examples)

Step-by-step explanation:

The order pair would be where the two lines intersect perpendicularly with each other forming a 90° angle
