Answer:
68
Step-by-step explanation:
Total mile cycled, d(t) ;
d(t) = 12t + 20
At d(4)
t = 4 ;
We have;
d(4) = 12(4) + 20
d(4) = 48 + 20
d(4) = 68
After, 4 hours of cycling, Joanna cycled a total distance of 68 miles
Answer:
c
Step-by-step explanation:
c because 12.50x4=50 and she still had money left
Let s and a represent the position of Sal and Amir respectively.
s=.75+4.5t and a=-.25+6.7t
When Sal catches Amir, s=a so we can say.
-.25+6.7t=.75+4.5t subtract 4.5t from both sides
-.25+2.2t=.75 add .25 to both sides
2.2t=1 divide both sides by 2.2
t=5/11 hours
t≈0.45 hours (to nearest hundredth of an hour)
Salutations!
