Question

Two cars start driving in the same direction from the same place. If one travels 53 mph and the other 59 ?mph, how long will it take them to be 36 miles? apart?

Answer 1

The formula to use in this case is Distance = Rate x Time

 

Time is what we want to determine, so we have to rearrange the formula to Distance ÷ Rate

the Distance is 36 miles

the Rate will be the difference between the two speeds, that is 59mph - 53mph = 6mph

 

So, Time = 36m ÷ 6mph = 6 hours
