Please explain how to solve this problem A motorboat can maintain a constant speed of 45 miles per hour relative to the water. The boat makes a trip upstream to a certain point in 34 ​minutes; the return trip takes 26 minutes. What is the speed of the​ current?

The speed of the current is _ ​mile(s) per hour.

Distance upstream = (34-c)(39/60) miles

Distance downstream = (34+c)(29/60) miles

Equation:

distance = rate*time

distance up = distance down

(34-c)(39/60) = (34+c)(29/60)

Multiply both sides by 60 to get:

39(34-c) = 29(34+c)

39*34 - 39c = 29*34 + 29c

68c = 340

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1
