Formula used: Average speed = \(\frac{(p+q)*(ab)}{(qa + pb)}\)
where the ratio of the distances traveled is p:q
speeds at which the respective distances are traveled are a and b
Jake rides his bike for the first \(\frac{2}{3}\)rd of the distance and the remaining
\(\frac{1}{3}\)rd of the distance on foot, making the ratio of the distances 2:1(p:q)
Jake travels by bike at speed(a)=10mph and travels by foot at speed(b)=3mph
Substituting values of a,b,p, and q, we get the value for the average speed, as follows
Average speed = \(\frac{(2+1)*(10*3)}{(10 + 6)} = \frac{3*30}{16} = \frac{45}{8}\)
Therefore, the distance traveled by Jake is \(\frac{40}{60}*\frac{45}{8}\) = \(\frac{15}{4}\)(Option B)

D is miles from home to school
(2/3 D) / 10mph + (1/3 D) / 3mph = 40 / 60
2/30 D + 1/9 D = 40/60
D is miles from home to school
(2/3 D) / 10mph + (1/3 D) / 3mph = 40 / 60
2/30 D + 1/9 D = 40/60
