### Calculation Examples

Here are two examples showing how the calculator works, with step-by-step explanations.

**Example 1: Calculating Average Lap Speed**

**Step** |
**Calculation** |
**Result** |

**Number of Laps** |
**10** |

**Average Lap Speed (MPH)** |
$\frac{10 \times 2.5}{90 / 60}$ = 16.67 |
16.67 |

**Example 2: Calculating Total Race Time**

**Step** |
**Calculation** |
**Result** |

**Number of Laps** |
**8** |
