Ten. 24+26+28=78. then 78÷6=13. if there is three classes then you subtract 3 from 13 and that gives you 10
Answer:
60 km
Step-by-step explanation:
The closure speed of the trains is 30+30 = 60 km/h. Since their initial distance apart is 60 km, it will take 1 hour for them to collide.
The bird flies for 1 hour at 60 km/hour, so flies a total distance of 60 km before being crushed in the collision.
Not sure about the linear equation but Jeremy catches up in 3 min.
1. divide 33 by 3 = 11 so Gerardo runs 1 mile in 11min
2. 11-8 =3 so Jeremy catches up in 3 min
