Solution:
Given,
Speed 1 = 3 km/h
Speed 2 = 5 km/h
Speed 3 = 8 km/h
Time taken = 39.5 minutes
Total speed = 3 km/h + 5 km/h + 8 km/h
Total speed = 16 km/h
Now, convert speed into m/s:
By multipling the km/h from 0.278
16 km/h × 0.278 = 4.44m/s
Now, convert into seconds:
By multipling the minutes from 60
39.5 minutes × 60 = 2,370 s
Firstly recall the formula of distance:
Displacement = Speed × Time taken
Substitute known variables into the equation.
Displacement = 2,370 s × 4.44 m/s
Solve for displacement.
Hence, Displacement = 10522.8 m

monal kumar travels equal distance with speeds of 3 km/hr.5 km/hr and 8 km/hr and total time taken 39.5 min. find distance
A man traveled at 40 kmph. Had he increased speed by 16 kmph, he would have covered 80 km more at the same time. What is the actual distance travelled by him?
