Answer 1

480:8=60       480:6=80      80-60=20                                                                     Ответ:на 20 км

Answer 2

Task Solution:

To solve this problem, we can use the formula:

Distance = Speed × Time

Given: - Initial time taken = 8 hours - Initial distance covered = 480 km - New time taken = 6 hours

Let's calculate the initial speed and then find out how much the speed needs to be increased to cover the same distance in 6 hours.

Calculations:

Initial speed: - Initial distance = Initial speed × Initial time - 480 km = Initial speed × 8 hours - Initial speed = 480 km / 8 hours - Initial speed = 60 km/h

New speed to cover the same distance in 6 hours: - New distance = Initial speed × New time - 480 km = New speed × 6 hours - New speed = 480 km / 6 hours - New speed = 80 km/h

Answer:

The motorcyclist should increase their speed by 20 km/h to cover the distance in 6 hours.
