Best Answer

In all he will cover 40 km. To do so at an average speed of 10 kph means his total journey will take 4 hours. He has taken 3hr 20 min for the first part (30km @ 9kph), so he has 40 min to cover the final 10km. Required speed is therefore 10 x 60/40 ie 15 kph.

A motorcyle goes from 30kmhr to 9kmhr in 2 s what is its acceleration?

The acceleration of the motorcycle can be calculated using the formula: acceleration = (final velocity - initial velocity) / time. Substitute the values: acceleration = (9 km/hr - 30 km/hr) / 2 s. Convert the velocities to m/s, calculate the difference, and divide by time to find the acceleration in m/s^2.
