At noon a car leaves washington, d. c., headed for miami, florida, a distance of 1100 miles. the train travels at a speed of 60 mph. at 1 pm a second car leaves miami headed for washington d. c., traveling at 70 mph. at what time will the two trains pass each other?

I car starts at 12.00 noon

Distance between Washington and Miami = 1100 miles

Speed = 60 mph

Hence after 1 hour, I car will be at 60 miles from Washingon or (1100-60) = 1040 miles from Miame.

At 1.00 p.m. distance between two cars is 1040 miles.

Since cars travel at opposite directions, relative speed per hour = addition of two speeds = 60+70 = 130 mph

Distance = 1040 miles

Relative speed =130 mph

Hence time for their meeting = 1040/130 = 8 hours

i.e. At 9 p.m. both will meet.

the answer is. -82562234434584
