Correct answer gets 25 brainiest
lara and tim took different routes to travel from point a to point c. lara took the route along a, b, and c. tim took the route along a, e, d, and c. their routes with distances and times are shown.
which person's average speed is greater?

a) lara's, because her average speed is twice tim's average speed
b) lara's, because her average speed is three times tim's average speed
c)tim's, because his average speed is 0.6 miles/hour greater than lara's average speed
d) tim's, because his average speed is 0.2 miles/hour greater than lara's average speed

D (approximately)

Step-by-step explanation:

In total, Lara walked 6+2=8 miles in 1.5+1=2.5 hours, and thus her average speed was 8/2.5=3.2 miles per hour.

Similarly, Tim walked 2+4+6=12 miles in 0.5+1.5+1.5=3.5 hours, and thus his average speed was 12/3.5=3.42 miles per hour.

total amount of money that he should pay if he has not used his duty free exemption is $98

cost of 3 shirts if one cost at $8.50 is

cost of 2 dresses if one cost at $27.50 is  

cost of 1 pair of gold cuff at $17.50

so, total amount of money that he should pay if he has not used his duty free exemption is   $25.5+$55+$17.50=$98
