Answer 1

Distance covered by fly =   150 units

Step-by-step explanation:

Complete Question a fly start flying from 1 rider to another rider until rider meet at a speed of 120 unit per hr

find distance covered by fly

two scooter riders moving in opposite direction

Hence their speed adds up

Effective speed = 40 + 40 = 80 units / hr

Total Distance to be covered = 100 unit

Total ride time = 100/80  = 5/4 hr

Hence fly ride for 5/4 hr

Speed of fly = 120 unit/hr

=> Distance covered by fly = 120 * (5/4) = 150 units

Distance covered by fly =   150 units
