90 miles away from Becky and 120 away from Don
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= [tex]60miles/h \times t[/tex]
Speed of Don = 80 mile/hr
Distance covered by Don in t time , y= [tex]80miles/h \times t[/tex]
Distance between both of them of 210 miles.
[tex]x+y=210 miles[/tex]
[tex]60miles/h \times t+80miles/h \times t=210 miles[/tex]
[tex]140 miles/h\times t=210 miles[/tex]
[tex]t=\frac{210 miles}{140 miles}=1.5 hours[/tex]
It will 1.5 hours to Becky and Don to meet each.
