Chapter 2, Problem 49R

To determine

To Find:The number of days need by the cyclist to complete the trip.

Answer to Problem 49R

To travel $800\text{km}$ the cycle need 6 days.

Explanation of Solution

Given:

The range of the distance travel is $800\text{km}$

Time of the cycle travels per day is $\text{8}\text{h/day}$

Average speed of the cycle is $16\text{km/h}$

Calculation:

Science the average speed of the cycle is $16\text{km/h}$ and the cycle traveling time per day is $\text{8}\text{h/day}$ . Therefore the total distance travel by the cycle per day

  $\begin{array}{l}16\text{km/h}\times \text{8}\text{h/day}\\ \text{=}\text{128 km/day}\end{array}$

Now to travel $800\text{km}$ distance the cycle need

  $\begin{array}{l}=\frac{800\text{km}}{\text{128 km/day }}\\ =6.25\text{days}\end{array}$

That means, almost 6 days

Conclusion:

Hence, to travel $800\text{km}$ the cycle need 6 days.
