Please tell the answer with full solution

​

Answer 1

Answer:

Solution:

(ii) 25 km

Speed (s1) = 40km/h

Time (t1) = 15 mins = (15/60) hr

Distance d1 = (s1 × t1) = 40 × (15/60) = 10 km

Speed (s2) = 60 km/h

Time (t2) = 15 min = (15/60) hour

Distance (d2) = (s2 × t2) = 60 × (15/60) = 15 km

Total distance (d) = (d1 + d2) = 10 km + 15 km = 25 km
