Question

The speed of car increases by 2km after every hour.if the distanc travelled in the first hour is was 35 km.what was the total distance travelled in 12 hrs

Answer 1

here's your answer ___________⭐⭐

❄Speed increase in AP.

Common difference (d)= 2

No. of term = 12

↪First term (a)= 35.

12th term = a + 11d = 35 + 2*11 = 57.

↪Sum = (No.of terms /2) * (first term + last term)

Sum = (12 /2) *(35 + 57) = 552.

↪Total distance traveled = 552 Km.
