Plz tell me answer and explain how i could get the answer.

  349.5 miles

Step-by-step explanation:

Use the formula distance (d) = rate (r) x time (t):

Since there are two different rates and times so solve each one separately and then add them together.

4a. is 3 miles every hour

4b. is 1/3 of an hour per mile

step-by-step explanation:

v = 1/3 a^2h

step-by-step explanation:

if the height is 57.7cm and the height of the slant edge is 18.2cm, then the volume is 1/3 a^2h.
