Sarah and Hillary decided on a bet. The person whose racecar passes the finish line wins a ticket to Egypt for the summer.
Sarah starts ahead of Hillary by 1 hour. The total distance that Sarah has travelled is 70 miles. Racing at the same speed as Sarah, Hillary manages to cover 35 miles. What was the speed?
Jim is left with $16 in his pocket, but he can't remember how much he had originally. He left a club with this amount on the fifth day. The club charged him an x amount of dollars on the first day to get in. Then it charged him half as much to get out. How much did Jim originally have on the first day?
