A boat moving at a constant speed travels 15 meters in 8 seconds. How far does it travel in 40 seconds?
0 75 meters
53 meters
335 meters
0 480 meters

75m

Explanation:

Given parameters:

Distance covered by the boat = 15m

Time taken = 8s

Unknown:

Distance covered by the boat in 40s  = ?

Solution:

To solve this problem, we need to find the speed of the boat first;

    Speed =

Insert the parameters and solve;

    Speed  = m/s

Now;

The boat will travel;    

    Distance  = speed x time

    Distance =    x 40  = 75m
