Two trains leave a city at 3 P.M. One train goes east at a constant rate of 70 mph. The other goes west at a rate of 62 mph. How long will it take the trains to be 528 mi. apart?plzzz help me

Answer:4 hoursStep-by-step explanation:The general formula for distance, rate and time is: d = rt, where distance is the product of rate multiplied by time Given that one train is moving at a rate of 70 mph and one is moving at a rate of 62 mph in the opposite direction, the combined distance over time is equal to 528 miles.  Using the variable 't' for time: 70t + 62t = 528 Combine like terms: 132t = 528 Divide both sides by 132: 132t/132 = 528/132  or t = 4 hours
