Question

How to calculate time if we have the distance and speed (kilometers per hour) in TypeScript

Answer 1

// Initialize distance and speed
const distance: number = 30; // (in km)
const speed: number = 90;    // (in km/h)

// Check to avoid division by zero
if (speed <= 0) {
  throw new Error("Speed must be greater than zero.");
}

// Calculate time
const tm: number = distance / speed;
console.log(`Time required: ${tm.toFixed(2)} hours`);

// Optional: convert to hours and minutes
const hours: number = Math.floor(tm);
const minutes: number = Math.round((tm - hours) * 60);

console.log(`Which is approximately ${hours} hours and ${minutes} minutes.`);


/* 
run:

Time required: 0.33 hours
Which is approximately 0 hours and 20 minutes.
