Johnny and his father go fishing at 5 AM. After motoring 6km upstream, Johnny writes a letter to his friend, puts the letter in a bottle. and drops it in the river. The bottle floats in the current and reaches 7:40 AM to the point where Johnny and his father began their trip. If the speed of the boat in still water Is 9 km/hr, what is the speed of the river current?

e) none of the above because the measure of angle cba is 101°

hello :

by applying the distributive property :

6 × 4.3 = 6 × ( 4 + 0.3 )

            =   (6 ×   4) + (6 ×   0.3)

            = 24 + 1.8

6 × 4.3 = 25.8

168

step-by-step explanation:

first off, we know that he drove 3.5 hours at a rate of 48 mph.

knowing that, we want to see how many miles he drove all-together.

in this case, we can just multiply 48 by 3.5.

48 * 3.5 = 168
