WILL GIVE BRAINLIEST! At 8:00 A. M., a train leaves a station and travels at a rate of 44 mph. At 9:00 A. M., a second train leaves the same station on the same track and travels in the direction of the first train at a speed of 64 mph. At 10:00 A. M., how far apart are the two trains?
mi

The speed of first train is 48 mph and the train travels for 2 hours before 10 AM. We know that DISTANCE = SPEED * TIME

DISTANCE =48*2
DISTANCE =96 miles

The speed of the second train is 64 mph and it travels for 1 hour before 10 AM.

So, the distance is 32 miles because 96 miles subtracted by 64 miles is 32.

The graph isn’t that clear

First step is to get rid of the square root. remember that a square root is the same as raising to the (1/2) power. see below: multiply exponents per exponent rules to get: remember you subtract exponents from the denominator and add exponents in the numerator so: simplify further: so a is the correct choice. if you don't understand this google exponent rules and it will you understand. look at the image results.
