Chapter 4.7, Problem 62STP

To determine

To choose:The correct option for the time taken by the giant tortoise to travel 0.8 mile.

Answer to Problem 62STP

The time taken by the giant tortoise to travel 0.8 mileis $t=\frac{0.8}{0.17}\text{ hour}$ . The correct option is (F).

Explanation of Solution

Given:

The travelling rate of the tortoise = 0.17 mile per hour.

The distance to be travelled = 0.8 mile.

Calculation:

The speed of the giant tortoise s = 0.17 mile per hour.

The total distance to be covered d = 0.8 mile.

The total time can be calculated from the relation

  $\text{Time}\text{=}\frac{\text{Distance}}{\text{Speed}}$

  $t=\frac{0.8}{0.17}\text{ hour}$

Therefore, the time taken by the giant tortoise to travel 0.8 mile is $t=\frac{0.8}{0.17}\text{ hour}$ . The correct option is (F).
