two and a half hours, 200/80 = 2.5
At an interest rate of 5 percent, $200 would earn $10 in one year.
4 workers would need 40 hours to paint 200 trucks, so 20 workers would paint your 200 in 8 hours.
200 miles per hour
she traveled 200 miles on Sunday and 250 miles on Saturday
Distance = Rate * Time or, for our purposes, Rate = Distance/Time Rate = 200 miles/4 hours = 50 miles per hour ==============
two and a half hours, 200/80 = 2.5
200 / 25 = 8 hours
200 miles
80 miles per hour. All you have to do is divide 200 by 2.5.
About 8.3 mph at that rate of travel.
4 hours.
2 1/2 hours.
2 and 1/2 hours
Distance = Rate * Time Algebraically manipulated for our purposes. Time = Distance/Rate Time = 200 miles/70mph = 2.9 hours .9 * 60 = 54 so, 2 hours and 54 minutes ==================
Getting a unit rate basically involves dividing one quantity by another quantity. In this case, it would make sense to divide the number of miles by the number of hours; that would give you a number of miles per hour, in other words, a speed.You could also divide the hours the other way round; in this case, you would get hours per mile - in other words, the number of hours it takes you (on average, in any case) to advance a mile. It isn't very common to divide this way, though.
hours are time, and miles are length
