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.

If y is directly proportional to x squared <br> and y = 3 when x = 2, what is y when x = 8?
Anestetic [448]

Answer:

<u><em>y = 63</em></u>

Step-by-step explanation:

<em>y is directly proportional to x²</em>

<em>As given,</em>

<em>when y = 3 => x = 2</em>

<em>So, 3 = 4 - 1</em>

<em>Which means the relation can be written as :-</em>

<em>y = x² - 1</em>

<em></em>

<em>Substituting x = 8</em>

<em>y = (8)² - 1</em>

<em>y = 64 - 1</em>

<u><em>y = 63</em></u>
