Answer:
Step-by-step explanation:
You can multiply the numerator and denominator by 2
(4.5/5.5)(2/2)=9/11
A=-.25+6.7t, s=.75+4.5t when Amir catches up a=s so:
-.25+6.7t=.75+4.5t add .25 to both sides
6.7t=1+4.5t subtract 4.5t from both sides
2.2t=1 divide both sides by 2.2
t=10/22 hr
t≈0.45 hr (to nearest hundredth)
31/7 = 4 3/7.....3/7 is less then 1/2....so the closest integer is 4
