What I did to find the answer is that I divided 96 the speed by 11/2 hours which is 90 and then I multiplied by answer by 1 hour which is 60 and found that the speed is 64 miles per hour
Answer:
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
