/**
 * Distance Traveled
 * Use the 'reduce' helper to find the sum of all the distances traveled. 
 *  Assign the result to the variable 'totalDistance'
 */

const trips = [{ distance: 34 }, { distance: 12 } , { distance: 1 }];

const totalDistance = trips.reduce((total, trip) => {
  total += trip.distance
  return total;
}, 0);

console.log(totalDistance);
/ Result is: 47
