A race car travels 950 km around a circular sprint track of radius 1.343 km. How many times did it go around the track?

Circumference = pi*2r = 3.14 * 2.686 = 8.44 km.

950km/(8.44km/rev) = 112.6 revs.

To find out how many times the race car went around the track, we need to find the circumference of the circular sprint track and then divide the total distance traveled by the circumference.

The formula to find the circumference of a circle is given by C = 2πr, where C represents the circumference and r represents the radius of the circle.

In this case, the radius of the track is given as 1.343 km. Therefore, the circumference of the track can be calculated as:

C = 2π × 1.343 km = 2 × 3.14159 × 1.343 km ≈ 8.448 km.

Now, we can divide the total distance traveled by the car (950 km) by the circumference of the track (8.448 km) to find the number of times it went around:

Number of laps = Total distance traveled / Circumference of the track
= 950 km / 8.448 km
≈ 112.49.

Since the car cannot complete a fraction of a lap, we should round the number of laps down to the nearest whole number. Therefore, the race car went around the track approximately 112 times.
