Bernie left home riding his bike at a rate of 15 mph charlie left one hour later biking at a rate of 20 mph how long will it take charlie to catch up with bernie

Bernie left home riding his bike at a rate of 15 mph.

Charlie left one hour later biking at a rate of 20 mph.

Bernie  distance = 15*t  (time is represented by t)

Charlie distance = 20*(t-1)  (he left after 1 hour)

15t = 20t - 20

-5t = -20        

t = 4

4*15 = 60

when t = 3 hours

3*20 = 60    

i think it's either c or d

step-by-step explanation: the entire question is extremely odd. 04 obviously refers to the interest rate. honestly i will say the answer is c. because the (2 x 12) part would mean it's compounded semiannually. i'll say choose c.

by definition, an arc subtended by a central angle of some given measure has the same measure. so .
