Question

2 trains 200 km apart move toward each other at 50 km/hr each

wasp takes off from one train flying st towards other at 75 km/hr

wasp collides with first train and bounces off and flies back to first train

repeats process until trains collide and wasp is squashed

what is the total distance wasp traveled until it's death?

Answer 1

distance=rate*time

d=rt

the wasp flies until it is squashed by the trains

how long does the wasp fly for ?

the wasp flies until the trains collide

when do the trains collide ?

200=50t+50t

200=100t

t=200/100

t=2 hours

in 2 hours each train travels 100 kilometers and then collide

the wasp flies for 2 hours at 75 km/hr

d=r*t

d=75*2

d=150 kilometers

the wasp  traveled 150 kilometers before it got squashed
