Answer:
Return trip travel time: 7h
Step-by-step explanation:
Let d be the distance.
Index 1 refers to initial trip, index 2 refers to the return trip.
v1=70mi/h
v2=40mi/h
t2=t1+3h, or t1=t2-3h (travel times)
d=v1×t1=v2×t2
v1×(t2-3)=v2×t2
v1 t2 -3 v1=v2 t2
v1 t2 - v2 t2=3 v1
t2(v1-v2)=3v1
t2=3v1/(v1-v2)
Or
t2=3×70/(70-40)=3×70/30=7h

Answer:
He lead the race for 1.5 miles
Step-by-step explanation:
4 tenths is equal to 4/10 = 0.4
0.4*2.5 miles = 1 mile
Lenox took the lead after the first mile of the race.
Se he lead the race for
2.5 miles - 1 mile = 1.5 miles
Which is equal to 60% of the whole trajectory.
