Can you please explain how to get an answer for this question and what formula to use step by step and why.

"In a race you first ride a bicycle at an anverage speed of 18.4 mi/h for 19.5 miles, then you must run for another 6.5 miles.

Randomized Variables:

v1,ave= 18.4mph

d1= 19.5mi

d2= 6.5 mi

With what average speed, in miles per hour, must you run if your average speed for entire race is to be 13.4 mi/hr? "
