Answer:
3.2 miles per hour
Step-by-step explanation:
Time=75 minutes=75/60=5/4=1.25 hours
Speed=Distance/time=4/1.25=3.2 miles per hour
David's jogging rate is 3.2 miles per hour.
72 = 1/2 (16x) because the area of a triangle is 1/2 (bh) and the height is x and the base is 16 and the area = 72 so solve for x to get base.
x=3, you can find this by using finding common bases for equation b because 243=3^5. Because of that you can get rid of three on both sides to get the equation 2x-1=5 and then just solve for x to get x=3. For the first equation 5^3=625 so that also proves x=3.
