Question

a car travels 300 metre the first second 420 the next minute so on in and automatic sequence was the total distance the car travels in 10 minutes​

Answer 1

Answer:

Distance traveled in 10 minutes = 8.4 km

Step-by-step explanation:

Distance traveled is in AP with a= 300 and d = 420 - 300 = 120

Distance traveled in 10 minutes = n/2*(2a+(n-1)d) = 10/2 (2*300 + 9*120)

= 5 * (600+1080) = 8400 m = 8.4 km
