Let's dissect this word problem into mathematics.
John is traveling to a client meeting. He has to travel 100 miles (=100) and is driving at a speed of 60 miles per hour (60x).
Let's work with this first. . Let's simplify that: , which simplified, is or . To translate that fraction into minutes, we'd simply multiply everything to get a denominator of 60. So, and . He spent 1 hour and 40 minutes driving. Add that to 9:00AM and you get 10:40 AM.
John reached at 10:40 AM. :)
