### Distance from Speed and Time

Integer division separates higher decimal/time units, while `%` returns the remainder. These two operations let a program isolate digits or split a total number of seconds/minutes into components.

['Decide which part comes from division and which part comes from the remainder.', 'Before printing, output only the computed result and do not add explanatory text that is absent from the required format.']

ANSWER Solution

const fs = require('fs');
const input = fs.readFileSync(0, 'utf8').trimEnd();
let [v, t] = input.trim().split(/\s+/).filter(Boolean).map(Number);
let result = v * t;
console.log(Number.isInteger(result) ? result.toFixed(1) : result);
