Question 675768
Sam leaves for the store on his skateboard at 8 mph. His skateboard breaks when he gets to the store, so he immediately goes home at a speed of 4 mph. What is the round trip distance if it took 2 hours?
---------------
Avg speed for the round trip = 2*8*4/(8+4) = 64/12
Avg = 16/3 mi/hr
d = r*t = 2*16/3
RT distance = 32/3 miles
