Johnny travels a total of one hour to and from school. On the way there he jogs at 5 miles per hour and on the return trip he gets picked up by the bus and returns home at 21 miles per hour. How far is it to the school? | [
"6.5 miles",
"10 miles",
"4 miles",

Average speed for round trip = 2*a*b/(a+b), where a,b are speeds
so, average speed was = 2*5*21/(5+21) = 6.5m/hr
the distance between schoolhome should be half of that. ie. 6.5 miles
