Question

Find the total distance covered by a car in 20minutes with a non uniform speed of 50km/hr for first 10minutes and then with a speed of 60km/hr for next 10minutes

Answer 1

Answer:

55/3

Step-by-step explanation:

We are given that the car has been traveling for about 20 minutes approximately in which the first 10 minutes where driven with different speed by the next 10 minutes with different speed .

Latest first calculate the distance traveled in the first 10 minutes:-

D 1 = s \times t = speed is 50 km per hour and time is 10 minutes changing time into hour \frac{10}{60} = \frac{1}{6} hr ⇒ 50\times \frac{1}{6} = \frac{50}{6}km

D 2= s \times t =Speed is 60 km per hour and time is 10 minutes again which equals \frac{1}{6} hr

D 2 = 60 \times \frac{1}{6} = 10 km

Adding the two distances to find the total distance = \frac{50}{6} +10 = \frac{110}{6} = \frac{55}{3} km.
