Problem Statement

A plane flew 3200 km in 4 hours. What distance will a motorcyclist travel if their speed is 1/10th of the plane's speed?

Solution

To find the distance the motorcyclist will travel, we need to determine the speed of the motorcyclist and then calculate the time it will take for the motorcyclist to cover the distance.

Let's start by finding the speed of the motorcyclist. We know that the speed of the motorcyclist is 1/10th of the speed of the plane. Since the plane flew 3200 km in 4 hours, we can calculate the speed of the plane as follows:

Speed of the plane = Distance / Time = 3200 km / 4 hours = 800 km/h

Now, we can calculate the speed of the motorcyclist:

Speed of the motorcyclist = 1/10 * Speed of the plane = 1/10 * 800 km/h = 80 km/h

So, the speed of the motorcyclist is 80 km/h.

Next, we need to calculate the time it will take for the motorcyclist to cover the distance. We can use the formula:

Time = Distance / Speed

Since we don't know the distance the motorcyclist will travel, let's represent it as 'D'. The time it will take for the motorcyclist to cover the distance 'D' can be calculated as:

Time = D / 80 km/h

Since we know that the time taken by the plane to cover the distance is 4 hours, we can equate the time taken by the motorcyclist to 4 hours:

D / 80 km/h = 4 hours

To find the distance 'D', we can rearrange the equation:

D = 80 km/h * 4 hours = 320 km

Therefore, the motorcyclist will travel a distance of 320 km.

Answer: The motorcyclist will travel a distance of 320 km.
