Answer 2

Step-by-step explanation:

In first case, Speed = 80 km per hour

Time = 15 min = 15/60 =1/4 hr (1 hour = 60 minutes)

Distance or d1 = Speed × Time = 80 ×1/4 = 80/4 =20 km

In second case, Speed = 100 km per hour

Time = 15 min = 15/60 =1/4

(1 hour = 60 minutes)

Distance or d2 = Speed × Time = 100 × 1/4 = 100/4 =25 km

So, Total Distance = d1 + d2 = (20 + 25) km = 45 km

The total distance covered by the car is 45 km.
