Question

A car moves with a speed of 40 km/h for 30 min and then with a speed of 60 km/h for 30 min. calculate​

Answer 1

Explanation:

1st case,

Speed = 40 km/hr

and time taken = 15 min =15/60 =0.25\ h

So, distance = 0.25\times 40 =10 km

Case 2nd,

Speed = 60 km/h

Time taken = 15 min = 0.25 h

So, Distance travelled = 0.25\times 60 =15 km

So, total distance = 15 + 10 = 25 km
