On a bike ride, calvin starts at home and goes up a long hill for 30 minutes at just 6 mph. at the top, he turns around and ride
omeli [17]

Answer:

<u>9 mph</u>

Step-by-step explanation:

Calvin's first leg of the trip took 0.5 hr (30 minutes) at 6 mph.  That means he travelled (0.5hr x 6 mph =) 3 miles.  He travelled 3 miles on the return trip, by definition (same path home).  At 18 mph, 3 miles would take (3 miles/18 mph =) 0.1667 hours.  That makes a total of 6 miles and (0.5 + 0.1667=) 0.6667 hours.

(6 miles)/(0.6667 hours) = 9 mph is Calvin's average speed for the round trip.
