<human>:  If Natasha was going 10 mph over the speed limit and it took her an hour to arrive at her destination that was 60 miles away, what was the speed limit?
<bot>: How fast was Natasha driving? ** Natasha was driving at 60 miles / 1hr = <<60/1=60>>60 mph
What was the speed limit? ** The speed limit was 60mph - 10 mph = <<60-10=50>>50 mph
