It takes Pam 4 1/4 to drive to the beach. Jim can drive to the beach in 1/2 of the times it takes Pam. How many hours does it take Jim to drive to the beach?

The time it takes Jim to drive to the beach is 2 1/8 hours.

Step-by-step explanation:

The amount of time that it takes Pam to drive to the beach is 4 1/4 hours. Converting 4 1/4 hours into improper fraction, it becomes 17/4 hours

Jim can drive to the beach in 1/2 of the times it takes Pam. This means that the time it takes Jim to drive to the beach would be

1/2 × 17/4 = 17/8 hours.

Converting 17/8 hours to mixed fraction, it becomes 2 1/8 hours

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5
