A boat travels for 7 hours. if it travels 4 hours downstream and 3 hours upstream. ten t covers a distance of 116 km. but if it
nadya68 [22]
Speed = Distance / Time
Distance = Speed*Time

For this problem, we should bear in mind that current speed has an impact on the boat speed...

for upstream, the boat goes against the current, and so its speed is

U = V - C

where V is the speed of the boat
C is the current speed

for downstream, it will be:

D = V + C

Convert the problem into mathematical equations:

4D + 3U = 116
3D + 4U = 108

4(V+C) + 3(V-C) = 116
4V + 4C + 3V -3C =116
7V + C = 116

3(V+C) + 4(V-C) = 108
3V + 3C + 4V - 4C = 108
7V - C = 108

Solving the equations:

7V + C = 116
7V - C = 108

14V = 224
V = 16km/hr —-> speed of boat

to get C:
7(16) + C = 116
C = 4km/hr

How do you solve the compound inequality?
NikAS [45]

Step-by-step explanation:

To solve a compound inequality, first separate it into two inequalities. Determine whether the answer should be a union of sets ("or") or an intersection of sets ("and"). Then, solve both inequalities and graph.

Hopes this helps.

Austin is riding his dirt bike at a speed of 350 feet per minute. How many yards would he have traveled in 2.5 hours? (HINT: 3 f
Harrizon [31]

Answer:

17,500 yards

Step-by-step explanation:

Speed of Austin's bike = 350 ft per minute

Given 3 feet in 1 yard

Now converting speed from  ft/min to yard per minute

3 feet equal 1 yard  (dividing both side by 3)

1 feet equals 1/3 yards

350 ft equals 350*1/3 yards

350 ft equals 350/3 yards

speed of bike in yards per minute = 350/3 yards per minute

______________________________________

Time for which bike traveled = 2.5 hour

one hour has 60 minutes

2.5 hour has 60*2.5 minutes

2.5 hour has 150 minutes

Time for which bike traveled in minutes = 150 minutes

________________________________________

formula for distance = speed * time

substituting value of  speed and time in above equation we have

distance =  350/3 * 150 = 17,500 yards

Distance traveled by Austin's bike in 2.5 hours is 17,500 yards.
