Answer 1

Answer:

Step-by-step explanation:

1. answer is 667/168

2. answer is 529.2

Step-by-step explanation:  speed = 252 / 5 km / h

distance = 200 km 100m= 200km 100 / 1000 = 200 1/10km = 2001/ 10 km

time = d/ s = 2001 / 10 ÷ 252 / 5 (÷ means fraction wala divide)

= 2001/10 × 5 / 252 = 2001/ 504

= 667/168hr or 3 163/168 hr

2. time = 10 1/2hr = 21 / 2hr

speed = 50 2/5km / hr = 252/2 km /hr

distance= t × s = 21 / 2 × 252/5

= 2646 / 5 = 529.2km
