Answer:
Step-by-step explanation:
744 total distance
Answer:
3 km
Step-by-step explanation:
Let x be the distance traveled at each speed.
Speeds are 10 km/hr, 30 km/hr and 8 km/hr.
t1 = x/10
t2 = x/30
t3 = x/8
total time is 15.5 min (t) = 15.5/60 hr
t = t1 + t2 + t3
=> 15.5/60 = x/10 + x/30 + x/8
=> 31 = 12x + 4x + 15x
=> 31 = 31x
=> x = 1 km
Total distance traveled = 3 km.
