3 A Car moves with a speed of 40 km/hin
15 minutes and then with a speed of 60 km/h.
Bornext 15 mins. Find the foral distance covered
By the car.​

Answer 1

Answer:

speed =d/time

$40 = \frac{x}{15 \times \frac{1}{4} } \\ 4 \times 15 = x \\ 60km = x$

$60 = \frac{x}{15 \times \frac{1}{4} } \\ 15 \times 15 = x \\ 225km = x$

Therefore the total distance is

$d1 + d2 \\ 60 + 225 \\ 285km$
