GIVING BRAINLIEST! Jeremy drove 240 miles on his vacation. He drove an average of 1.5 times faster on the second 120 miles of his trip than he did on the first 120 miles of his trip. Which
expression represents the time he spent driving? Let x = his speed on the first half of the trip.

a. 240/x
b. 200/x
c. 200x
d.300/x

b. 200/x

Step-by-step explanation:

Hi, to answer this question we have to analyze the information given:

First half speed= x

Second half speed= 1.5 x (1.5 times faster on the second 120 miles of his trip)

Since:

Time = distance /speed  

Total time = 1st half time + 2nd half time

Replacing with the values given

Total time =120/ x + 120/1.5x

Total time = 180/ 1.5x + 120 /1.5x

Total time = 180+120/1.5x

Total time = 300/1.5x = 200/x

the terms of a geometric sequence can be found by beginning with the first term and multiplying by the common ratio repeatedly. a recursive formula for a geometric sequence with common ratio r is given by an=ran−1 a n = r a n − 1 for n≥2 n ≥ 2 .
