Question

A car move with speed of 80km/h for 30 mins and then with a speed of 120km/h for the next 30 mins, calculate the total distance covered by the car
​

Answer 1

Answer:

100 km

Step-by-step explanation:

S1 = 80 km/h

S2 = 120 km/h

T1 = T2 = 1/2 h

We know,

Distance = Speed x Time

Thus, D1 = 80 x 0.5

         D1 = 40 km

D2 = 120 x 0.5

     = 60 km

Therefore,

Total Distance = 40 + 60

                        = 100 km
