7. which of the following relations is correct? (a) speed = distance × time(b) speed = distance by time(c) speed = time by distance(d) speed = 1 by distance × time8. The SI unit of speed is(a) km/min(b) m/min(c) km/h(d) m/s9. A car moves with a speed of 40 km/h for 15 minutes and then with a speed of 60 km/h for the next 15 minutes. Thetotal distance covered by the car is :(a) 100 km(d) 25 km(b) 15 km(c) 10 km10. When a particle covers equal distances in equal intervals of time, it is said to be(a) moving with uniform speed(b) moving with oscillation(c) moving with acceleration(d) at rest please help me
