Answer:

24,968 revolutions

Explanation:

We need to find the circumference of the wheel in order to determine how many revolutions it will take to cover a distance of 78.5 km. The formula for circumference is:

Circumference = π x diameter

Substituting the given values, we get:

Circumference = 3.14 x 1 = 3.14 meters

Now, we need to convert the distance of 78.5 km to meters, so that we can compare it with the circumference of the wheel.

1 km = 1000 meters

Therefore, 78.5 km = 78,500 meters

To find the number of revolutions taken by the wheel, we need to divide the distance traveled by the circumference of the wheel:

Number of revolutions = Distance ÷ Circumference

Number of revolutions = 78,500 ÷ 3.14

Number of revolutions = 24,968.15

Therefore, it will take approximately 24,968 revolutions for the wheel of the truck to cover a distance of 78.5 km.

Hopes this helps
