A car moves with a speed of 40km/h for 15 minutes and then with a speed of 60 km/h for the next 15 minutes. Find the total distance covered by the car in these 30 minutes.

Solution:

$ Distance = Time \times Speed$

Distance₁ = $15 min \times 40 kmph$

                 = $\frac{15}{60} h \times 40 kmph$

= 10 km

Distance₂ = $15 min \times 60 kmph$

                 = $\frac{15}{60} h \times 60 kmph$

= 15 km

Total distance = 10 km + 15 km = 25 km
