Question

A car moves with a speed of 20km/hrs for 5 minutes and then with speed of 60 km /hrs for the next 10 minutes the total distance covered by car​

Answer 1

Answer:

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 $(d) = (d1 + d2) = 10 km + 15 km = 25 km$
