Question

car leaves town at 30 kilometers per hour how long will it take second car traveling st 135 kilometers per hour to catch first car if it leaves 1hour later 

Answer 1

Ok D = rate x time You need to find when the two distances are equal. 135xt = 30(t +1) 135t = 30t + 30 105t = 30 t = 30/105 = 2/7 After 2/7 of an hour, the 2nd car will catch up.
