Carlos is going on a boat tour. The boat will travel a total distance of 20 kilometers during the 5 dash hour tour. If the boat travels at a constant speed during the tour, what distance in kilometers should the boat travel in 2 hours?

8 km

Step-by-step explanation:

We begin by finding the speed of the tour boat;

Speed = distance/ time

= 20 / 5

= 4km/hr

To find distance traveled by the boat in 2 hrs;

Distance = speed * time

= 4 * 2

= 8 km

8km

Step-by-step explanation:

Given parameters:

Distance covered during the first 5hours  = 20km

Time taken to cover this distance  = 5hours

  Since ;

              Speed  =

               Speed  =   = 4km/hr

Given also that the car traveled with a constant speed throughout the tour and we have found the speed to be 4km/hr;

            Distance covered in 2hrs;

                Distance  = speed x time

                                  = 4 x 2

                                    = 8km

answer: 80,000

step-by-step explanation:

the population doubles every day.

10,000*2=20,000 day 4

20,000*2=40,000 day 5

40,000*2=80,000 day 6
